INV Series

INV Series, Rugged Sine-wave Inverter for Sub-Station and Military Applications

The Behlman INV Series DC to AC Inverters deliver clean, regulated AC power from DC, in a rack mount chassis. The standard unit is available as a simple DC-AC inverter. With Option D1, a transfer circuit will switch the load to an AC input upon loss of the DC input or inverter, or you could choose Option A1, with AC as the primary power with a transfer to the DC input upon loss of the AC.

Both options come with front panel indicators and three form “C” contacts for alarms.

If you have an application where you require AC power from your batteries or DC source Behlman’s INV series is your best choice. Ideal for use where sensitive electronics require clean regulated AC.

DC to AC Power conversion

INPUT
Voltage:
DC:	48 VDC +/- 20% or 125 VDC +/- 20% or 250 VDC +/- 20% (INV1200) Maximum DC burden (full load) 40 amps DC @ 38 VDC, 15 amps DC @ 100 VDC or 7.5 amps DC @ 200 VDC

OUTPUT

Power:	1200 VA or 2500 VA
Voltage:	120 VAC +/- 5%, 60 Hz, isolated
Current:	10 Amps or 37 Amps
Crest Factor:	3:01
Power Factor:	100% of rated output into any power factor load
Distortion:	<3% THD typical Model INV1200
Line Regulation:	+/- 0.3% for +/- 10% line change
Load Regulation:	+/- 2.0%, no load to full load
Efficiency:	80-85% typical

PROTECTIVE CIRCUITS

Input:	Main circuit breaker
Constant Current:	Overload automatically causes voltage fold-back to provide maximum current without distorting output waveform
Short Circuit:	Short circuit overload electronically latches output open to protect load... power restored by cycling input power
Thermal:	Internal temperature sensor shuts off output to prevent heat damage
Bypass:	With Option D1, if unit fails, the AC input will be routed to the output with front panel bypass fuse

CONTROLS / INDICATORS

Power On/Off:	Circuit breaker
Indicators:	AC IN, DC IN, INVERTER
Bypass Fuse:	15 Amps

ALARM CONTACTS with OPTION A1 or D1

Contact closures:	AC IN, DC IN, Inverter OK
