Unipower Telecom’s
Gravitas IX12.5-115 and IX12.5-230 are sine wave Telecom Power Inverter
Systems which produce a maximum output of 12.5kVA at 115 or 230VAC,
50 or 60Hz. The system consists of a 5 rack-space-high (8.5 inches),
23-inch shelf which holds up to 5 hot-swap inverter modules with
outputs connected in parallel. In a 4+1 redundant mode it produces
10kVA output. The inverter modules operate off a nomimal 48VDC input
(42- 56VDC range), and each module produces 115VAC of power at 22A
or 230VAC at 11A full load. The system can be operated with up to
five modules. The output is a 50 or 60Hz, low-distortion sine wave.
Each module is protected by its own input and output circuit breakers,
is self-cooled by two fans, and has input, output and sync OK LEDs.
The AC output has six load circuit breakers on the front panel.
The AC load and DC input connections are made to terminals at the
rear of the system. The output is fully isolated from the battery
input. There is also a signal connector with a failure alarm output
and a sync output signal used for paralleling with another Gravitas
Power Inverter System. The Gravitas Power System has high surge
capability, up to 300%, which enables it to start motor loads. |
