Standard Features

Partial Option Selection

• High input power factor (>0.99) with low input THD-i (<3%).

• Low adaptability for linear and nonlinear load.

• Low audible noise system design (<55db).

• Double DSP controller for each individual power module.

•

• Digital control for all major UPS subassemblies including rectifier,

inverter, battery charger, and battery discharge.

• IGBT modules rather than discrete semiconductor components

are used in the power module for high reliability.

• Conformal coated boards for humidity resistance.

•

• Built in PDU circuit breakers for cabinet AC input, AC output and

maintenance bypass.

•

• Digital paralleling technology with very low circulating current

between power modules.

•

• Front access cabinet with both top and bottom cable connections.

•

• Each individual module is configured with an independent DSP

controller to avoid single point of failure risk.

• Generator-friendly interface.

••

• RS232, 485, and dry contacts all standard.

• VRLA batteries in a separate matching cabinet or in an open rack.

•

• VRLA batteries in modular drawers.

•

• Battery circuit breaker.

• SNMP communication card.

•

• Battery temperature compensation module.

•

• User replaceable air filter for dusty environments.

•

• Parallel operation kit.

•

• Input isolation transformer.

•

• Alternate remote shutdown / EPO configurations.

•

Battery cold start module (Allows the UPS to start on battery alone).

•

High Reliability Design

The low-loss integrated three-level IGBTs used in

each NERM-Series power module result in higher

efficiency and enhaced reliability due to lower

heatsink temperatures.

Module Features

Hot swap building block 12 KVA and 6 KVA modules @ 120/208 VAC

and 20 KVA and 10 KVA modules @ 220/380 VAC

• Independent control.

• Designed for parallel operation with active current sharing.

• Designed for (N+1) redundancy.

•

• Capable of hot swap.

•

• Automatic mechanical disconnection in case of failure or

maintenance.

NERM-Series Integrated

IGBTs boast Ultra-High

Reliability

Discrete IGBT devices in

competing UPSs are less

reliable and not as efficient
