APC by Schneider Electric ACCU100 Data Center Condensing Unit
Overview
The APC by Schneider Electric ACCU100 is a 200–240V commercial condensing unit designed for precision cooling infrastructure in data centers and critical facility environments. Built to CE and UL standards, the ACCU100 operates on 208–230V three-phase power — the kind of dedicated electrical service already present in most enterprise machine rooms and colocation facilities — eliminating the need for additional power conversion hardware at installation.
Rated for operation between -20°C and 45°C (-4°F to 113°F), the ACCU100 handles both frigid outdoor placement in northern climates and hot ambient conditions typical of rooftop or mechanical yard installations. That range matters in practice: a condensing unit that shuts down at 40°C ambient becomes the single point of failure for your cooling system on a hot summer afternoon.
Key Features
- 200–240V, 3-Phase Input: Draws from the same three-phase electrical infrastructure as your UPS and PDU gear, simplifying electrical coordination and reducing the number of circuit types a facilities team has to manage.
- CE and UL Listings: Dual certification covers both North American (UL) and European (CE) compliance requirements — relevant for multinational deployments or facilities subject to mixed regulatory audits.
- -20°C to 45°C Operating Range: Wide ambient tolerance supports outdoor condenser placement in climates with cold winters and hot summers without requiring supplemental heating or shade structures in most temperate regions.
- Large Cabinet Form Factor (approx. 1520H × 2200W × 1070D mm): The physical envelope — roughly 60" H × 87" W × 42" D — requires dedicated mechanical yard or rooftop allocation. Plan structural load capacity against the approximately 635 kg (1,400 lb) operating weight before specifying the mounting surface.
Integration and Compatibility
The ACCU100 is designed to pair with a compatible APC by Schneider Electric indoor air handler or Computer Room Air Conditioner (CRAC) unit as part of a split cooling system. Verify refrigerant line sizing, charge requirements, and the specific indoor unit model against APC's installation documentation before commissioning — split system performance depends on correct line set length and refrigerant charge, both of which are site-specific variables. Electrical connection requires a dedicated 208–230V three-phase circuit with appropriate disconnect and overcurrent protection sized to the unit's nameplate amperage.
Frequently Asked Questions
Q: What power supply does the ACCU100 require?
A: The ACCU100 requires a 208–230V, three-phase power input. A dedicated electrical circuit with appropriate disconnect and overcurrent protection is required — confirm breaker sizing against the unit's nameplate amperage prior to installation.
Q: What is the operating temperature range of the ACCU100?
A: The ACCU100 is rated for ambient operating temperatures from -20°C to 45°C (-4°F to 113°F), making it suitable for outdoor condenser placement in most temperate and subtropical climates.
Q: What certifications does the ACCU100 carry?
A: The ACCU100 is CE and UL listed, covering both North American and European regulatory compliance requirements.
Q: How heavy is the ACCU100 and what are its dimensions?
A: The cabinet weighs approximately 635 kg (around 1,400 lb) and measures approximately 1520H × 2200W × 1070D mm (roughly 60" × 87" × 42"). Structural load capacity of the mounting surface must be verified before installation.
Q: Does the ACCU100 work as a standalone cooling unit?
A: No. The ACCU100 is a condensing unit — the outdoor component of a split cooling system. It must be paired with a compatible APC indoor air handler or CRAC unit. Consult APC's system documentation for compatible indoor unit models and refrigerant line set requirements.
The ACCU100 is a large-footprint condensing unit — 635 kg, three-phase power, ~2200mm wide — so the infrastructure conversation has to happen before anything else. I've seen split cooling projects stall at commissioning because the mechanical yard wasn't sized for the condenser or the electrical panel didn't have a three-phase circuit available at the right amperage. Get those site constraints locked before the ACCU100 ships.
Technical Highlights:
- 3-Phase 208–230V Input: Aligns with standard enterprise electrical infrastructure — the same panel feeding your UPS gear can typically source this circuit, reducing the number of separate electrical service runs.
- -20°C to 45°C Ambient Range: Covers rooftop and mechanical yard placement across most North American and European climates without supplemental heating, keeping the installation simpler than units with narrower ambient ratings.
- CE and UL Dual Listing: A practical requirement for enterprise procurement — CE covers European facility audits, UL satisfies North American AHJ inspections; having both on one unit avoids substitution headaches in multinational rollouts.
Deployment Considerations:
- At approximately 635 kg operating weight, the mounting surface — rooftop, concrete pad, or mechanical platform — must be structurally certified for that load before installation begins. This is not a step to defer to the commissioning team.
- The ACCU100 is one half of a split system. Refrigerant line set length, charge, and indoor unit compatibility are all site-specific variables that must be resolved against APC's engineering documentation — the unit won't perform to spec if the line set is over-length or incorrectly charged.
The ACCU100 is the right specification for a new-build or capacity-expansion project where three-phase power is already on the mechanical yard and the indoor CRAC unit is already selected from the APC InRow or precision cooling family — not a drop-in replacement without verifying system compatibility first.
