The Behlman ACDC-1250 Inverter delivers 1250 VA of clean, regulated AC power in a 5.25” high rack mount chassis. It was designed to operate reliably in a utility or industrial environment where power surges and transients are a concern. In the event of loss of AC input the ACDC will automatically switch to your DC source in ZERO time. The ACDC can be factory set for AC or DC primary input operation mode. The ACDC Inverter continuously conditions the incoming power, providing a high quality sine wave output with very little distortion.
The ACDC Inverter is ideal for use in substations and utilities where sensitive station electronics require clean,
surge protected and regulated AC.
| Model | Power (VA) | Output Volts VAC (RMS) | Output Current (Amps) | Frequency (Hz) | Input (VDC) | Dimensions (19” Rack-Mount) |
|---|---|---|---|---|---|---|
| ACDC-1250 | 1250 | 120 | 10.4 | 60 | 48 VDC, 125 VDC or 120 VAC | 5.25”H X 19”D |
The ACDC Inverter has all the features our customers have come to expect from Behlman; a clean regulated sine wave output with excellent line and load regulation, high efficiency and low harmonic distortion in a compact enclosure. The ACDC Inverter contains a unique overload protection system that folds back the voltage to maintain maximum rated current without distorting the output waveform. The unit has LED indicators on the front panel and status and alarm contacts on the rear. These contacts can be utilized by a Supervisory Control And Data Acquisition (SCADA) system. In the event of an inverter failure the unit has an automatic bypass that switches in zero time to ensure that the output power is maintained
The ACDC Inverter is ideal for use in substations and utilities where sensitive station electronics require clean, surge protected and regulated AC.
