3kW in 2U rack from hot swap power system
The new TMN Series power system front ends from Unipower provide up to 3,000 watts at 24, 28 or 48VDC for distributed power systems.
A 2U high, 19 or 23in rack-mounting shelf is available which will accept two units in parallel for a 5000VA system or for N+1 redundant applications.
When operated in the shelf they are automatically paralleled.
They are fully isolated from the telecomms battery.
An input circuit breaker turns on the inverter and protects the battery from input faults.
An output breaker connects the inverter to the load bus (after synchronisation if the bus is live) and quickly disconnects the inverter in the event of an internal fault.
The inverter has a high surge capability (up to 300%) for starting loads such as motors, but the output breaker quickly trips if power attempts to flow back into a faulted inverter.
Front panel LEDs indicate inverter status and Form C relay alarm contacts are available on the back.
The units are self-cooled by internal fans. Request a free brochure from Unipower Europe ...
