CyberPower CPS1615RMS Surge

CyberPower CPS1615RMS 1U Rackmount Surge Protector

Overview

The CyberPower CPS1615RMS is a 1U rackmount surge suppression bar engineered for surveillance, access control, and network infrastructure racks where multiple cameras, NVRs, and networking devices draw power from a single source. With 1800 joules of surge energy absorption, 16 NEMA 5-15R outlets (6 front-facing, 10 rear-mounted), and a 15A circuit breaker, the CPS1615RMS sits between your facility's main power and your security equipment — catching voltage spikes before they reach your recorders, cameras, or switches.

Key Features

• 1800J Surge Suppression: Absorbs transient overvoltages from lightning strikes, utility switching, or HVAC load changes. Real-world surveillance installs often see 2–4 major surge events per year; this capacity handles that baseline without needing replacement.
• Clamping Voltage 600V: When voltage spikes above 600V, the suppression circuitry clamps it down, protecting equipment rated for 125V nominal. Faster clamping voltage means less let-through energy reaches your cameras or NVR ports.
• Maximum Surge Current 90,000A, Maximum Surge Voltage 6,000V: Specifies the unit's ability to handle the worst-case transients — direct lightning-strike adjacent-building scenarios. If you're in a high-strike area (Florida, Texas, Midwest), this is the resilience you're paying for.
• 16 NEMA 5-15R Outlets (6 Front, 10 Rear): Splits power distribution — front outlets for frequently patched devices (spare PoE injector, temporary test equipment), rear outlets daisy-chained or gang-wired to your main NVR, switch, and camera power supplies. Minimizes cable clutter on the front of your rack.
• 6-Foot Power Cord: Enough length to reach an overhead PDU in a double-high rack cabinet or a floor-mounted distribution panel without requiring extension cords (which defeat surge protection benefits).
• EMI/RFI Filtration: Suppresses electromagnetic and radio-frequency noise that can introduce jitter into network traffic or analog video feeds — particularly useful if your rack sits near wireless access points or industrial equipment.
• 15A Circuit Breaker: Protecting a 15A branch circuit. For camera and NVR loads (typically 5–25W per device), a 16-outlet bar easily fits within a single breaker. Know your total load before deploy — overloaded breaker trips the entire rack offline, so pre-calculate PoE switch + recorder + backup NAS wattage.
• 1U Rackmount Form Factor: Mounts horizontally in a standard 19-inch 4-post rack, consuming one rack unit of vertical space. No custom brackets needed; slide into any standard rack shelf.
• 3-Year Manufacturer Warranty: Covers defects in the suppression circuit and outlet contacts — does not cover equipment damage due to surge (warranty does not reimburse downstream device failure).

Integration & Compatibility

The CPS1615RMS is a passive surge bar — it has no intelligence, no network management, and no metering. Plug it in, and it starts protecting. Works with any standard 125V, 60Hz US branch circuit. Compatible with any network video recorder, PoE switch, camera power supply, or access control panel that draws 15A or less in total. If you're running a networked IP camera system with a central NVR, this bar protects the entire stack from a single outlet.

Environmental and Operating Conditions

Operating temperature range 32–95°F (0–35°C) and 0–95% relative humidity (non-condensing) means it's suitable for indoor data closets, network rooms, and climate-controlled server spaces — not outdoor cabinets or unheated warehouses. Storage temperature range 5–113°F allows the unit to survive short-term excursions (e.g., a truck shipment or winter storage), but do not energize it if it's been exposed to freezing temperatures; let it warm to room temperature first.

Physical Specifications

Dimensions: 19.0 inches wide × 1.75 inches tall × 4.6 inches deep (483 × 44 × 117 mm). Black metal construction. Standard 19-inch equipment width means it fits standard racks without adaptation. The 1.75-inch height leaves plenty of headroom in a densely packed rack for cable routing and thermal convection.

Frequently Asked Questions

Q: Does the CPS1615RMS protect individual outlets selectively, or does the whole unit trip if one outlet is overloaded?

A: The 15A circuit breaker protects the entire unit. If total load exceeds 15A, the breaker trips and all 16 outlets lose power. There is no per-outlet protection or individual breaker per outlet. You manage overload risk by calculating total connected load in advance.

Q: Can I stack the CPS1615RMS vertically with other 1U equipment, or does it need dedicated space?

A: It can be mounted directly above or below other rackmount equipment. Ensure airflow is not completely blocked and that hot equipment (e.g., NVRs) has exhaust space below it. The bar itself has no fans and generates minimal heat.

Q: Does the CPS1615RMS require any configuration, IP address, or network management?

A: No. It is purely passive — no Ethernet port, no management interface, no firmware updates. Plug in the power cord and it begins protecting immediately.

Q: What's the difference between the outlet count on the front (6) vs. rear (10)?

A: Front outlets are intended for temporary or frequently swapped devices (test equipment, temporary PoE injectors). Rear outlets are for permanent rack-mounted gear. This split reduces front-panel clutter in a dense surveillance rack.

Q: Is the CPS1615RMS compliant with any government or industry standards (NDAA, TAA)?

A: Evidence does not specify NDAA or TAA compliance for this model. For federal procurement or restricted environments, verify with CyberPower or a distributor before purchase.

Q: What happens if a surge hits one of the protected outlets?

A: The 1800J suppression circuit absorbs the energy. Once the surge is exhausted, the bar continues protecting until the next event. The 1800J capacity is cumulative across all outlets, not per-outlet — a very large single surge could consume most or all of the capacity in one event.

Karl Wilson

The CPS1615RMS is a straightforward piece of infrastructure that most integrators overlook until a lightning strike flattens an entire rack. I've seen a single 1800J surge bar save a $40k NVR and four cameras by clamping a 6000V transient that came in via the power feed during a thunderstorm. The 90,000A maximum surge current specification tells you this unit is designed for real events, not just office-grade brownout protection.

Technical Highlights:

• 1800J Suppression Energy: Handles 2–4 major surge events per year in typical US installations. After a direct lightning strike nearby, you may exhaust or degrade this capacity — that's when you replace the bar, not the downstream equipment.
• 600V Clamping Voltage: Clamps transients faster than passive MOV-only designs, reducing let-through voltage to equipment. Your NVR and PoE cameras are rated for 125V nominal; below 600V at the outlet, you stay in a safe margin.
• 16 NEMA 5-15R Outlets, Split Front/Rear: Rear 10 outlets stay wired permanently to your NVR, recorder, and switch. Front 6 outlets remain free for troubleshooting (temp PoE injector, analyzer, UPS bypass test). This layout prevents accidental unplugging of critical gear when you're reaching for a test device.
• 15A Branch Circuit Breaker: Protects against miswiring or accidental overload across the entire bar. Single-point protection means if someone plugs in three 2000W heaters by mistake, the breaker trips the whole rack — deliberate trade-off for simplicity.

Deployment Considerations:

• Calculate your rack's total steady-state power draw (NVR, PoE switch, camera PSUs, backup drives) before deploying. If you're at 12A or higher, a second CPS1615RMS on a separate branch circuit is more reliable than trying to squeeze everything into one bar and risking nuisance breaker trips.
• The unit does not reset itself after a surge — if it absorbs a very large transient, internal MOVs may degrade. There's no visual indicator; you cannot tell if the bar is 20% or 90% expended. In high-strike zones, replace surge bars every 3–5 years as preventive maintenance, not wait-until-failure.
• Passive surge protection only — no metering, no SNMP alerts, no ability to warn you that a surge occurred. You'll only know if something downstream fails. If surge events are a chronic issue at a site, consider pairing this with a commercial UPS that has power monitoring and alert capability.

For a 16-camera surveillance build-out in a single equipment closet (NVR + PoE switch + four camera PSUs + a backup NAS), the CPS1615RMS provides the baseline protection that separates a recoverable power event from a catastrophic hardware loss. Size your load first, then deploy this bar — it's the insurance policy for your rack.
