APC Smart-ups 500VA LCD 100V - SMT500J

APC by Schneider Electric SMT500J Smart-UPS 500VA LCD 100V Tower UPS

Overview

The SMT500J is APC's 500VA Smart-UPS designed for the 100V Japanese electrical standard, delivering regulated backup power in a desktop tower form factor that fits under or beside equipment racks without consuming rack units. At 27.8 lb (12.6 kg) with a non-rack-mountable chassis measuring 6.57 in (16.7 cm) in its primary dimension, this unit is sized for localized equipment protection — security head-end closets, small NVR deployments, or access control panels where a full rack-mount UPS would be oversized. The LCD front panel gives you at-a-glance status without pulling out a laptop or connecting management software, which matters in equipment rooms where quick visual checks are the norm.

The 100V input and output rating makes the SMT500J specific to Japanese-market electrical infrastructure. If your facility runs 110V or 120V North American circuits, this is the wrong unit — verify your site's supply voltage before ordering. For 100V environments, the matched input/output ensures connected equipment sees clean, regulated voltage rather than raw utility power.

The included 6 ft (1.8 m) power cable gives reasonable reach from a wall outlet or PDU without relying on extension cords, which is correct practice for UPS installations. The black chassis integrates without visual friction into standard equipment rooms. The non-rack-mountable form factor is a hard constraint — there is no tower-to-rack conversion kit referenced in available evidence, so plan for shelf or floor placement.

For uninterruptible power supplies in security and access control deployments, the Smart-UPS line from APC by Schneider Electric is a common choice among integrators. If you're sizing backup power for a multi-camera NVR or access control head-end, review your power and UPS planning load requirements before committing to a 500VA unit — runtime and load capacity depend on the connected equipment draw, and those specs should be confirmed against the manufacturer datasheet for this SKU.

Key Features

• 100V Input/Output: Matched 100V rating means equipment connected to this UPS receives the same voltage it expects from the wall — no conversion losses, no over- or under-voltage conditions on Japanese-spec gear.
• LCD Status Display: Front-panel LCD provides real-time status without requiring a connected PC or management app — useful for quick checks during physical inspections of equipment rooms.
• Desktop Tower Form Factor: At 6.57 in in its primary dimension and non-rack-mountable, this unit is designed for shelf or floor placement. It won't consume rack units, but it also can't be rail-mounted — confirm your installation space before ordering.
• 27.8 lb (12.6 kg) Chassis Weight: Substantial weight for a 500VA class unit — account for shelf load ratings if wall-mounting a shelf, and plan for two-person handling during installation.
• 6 ft (1.8 m) Power Cable: Standard cable length covers most equipment room layouts without requiring extension cords, which can introduce resistance and compliance issues in UPS circuits.

Frequently Asked Questions

Q: Is the SMT500J compatible with North American 120V electrical systems?

A: No. The SMT500J is rated for 100V input and output, specific to Japanese electrical infrastructure. North American facilities run 110V or 120V — this unit is not appropriate for those environments. Verify your site supply voltage before ordering.

Q: Can the SMT500J be rack-mounted?

A: No. The SMT500J is a desktop tower form factor and is not rack-mountable per available specifications. Plan for shelf or floor placement in your installation.

Q: What is the physical weight of the SMT500J?

A: The SMT500J weighs 27.8 lb (12.6 kg). Account for this when planning shelf installations and consider two-person handling during deployment.

Q: What power cable is included with the SMT500J?

A: A 6 ft (1.8 m) power cable is included, providing adequate reach for most equipment room outlet configurations without requiring extension cords.

Q: Where can I find the full runtime and outlet specifications for the SMT500J?

A: Runtime curves, outlet count/type, battery specifications, and communication interface details are available in the manufacturer's datasheet for the SMT500J, accessible on APC's product documentation site.

The SMT500J is a 100V-specific unit — that voltage rating is the first thing to confirm before it goes on an order. I've seen this model specified correctly for Japanese-market deployments and incorrectly quoted for North American sites; the 100V input/output is non-negotiable and there's no autosensing on this unit. At 27.8 lb in a tower chassis, it's a physically substantial piece of equipment for a 500VA class UPS.

Technical Highlights:

• 100V Input/Output Matching: Dedicated 100V in/out means no conversion stage — equipment draws exactly the voltage it's designed for, which matters for sensitive security electronics with tight voltage tolerances.
• LCD Front Panel: Local status visibility without a management connection reduces the time spent diagnosing power events during site inspections — a practical advantage in unmanned equipment rooms.
• Desktop Tower Form Factor: The non-rack-mountable chassis at 6.57 in keeps rack space available for active equipment while the UPS sits on a dedicated shelf — a reasonable trade in small security closets where rack space is constrained.

Deployment Considerations:

• Confirm 100V site supply before ordering — this unit will not operate correctly on 110V or 120V North American circuits, and the mismatch won't be obvious until equipment fails to receive correct voltage.
• At 27.8 lb, single-person installation onto a high shelf is a handling risk — plan accordingly and verify shelf load capacity before placement.

The SMT500J is the right fit for Japanese-infrastructure security deployments — small NVR head-ends, access control panels, or intercom head units on 100V circuits where a tower form factor is preferable to consuming rack space.
