Alpha 1000 units are fully configurable and can provide between one and 14 adjustable outputs. Up to seven modules – single or dual outputs – can be fitted with output voltages from 1.8V to 48V and output currents of up to 120 amps; no minimum loads are required. Inhibit, ACfail, current-share and DC-good signals are available as options.

The Alpha 1000 can deliver up to 1000 watts from –20°C to +50°C and derates at 3.3% of a degree from 50°C to 65°C. All models accept a wide range of input voltages – from 85VAC to 264VAC – and contain active PFC (power factor correction) circuitry to meet EN61000-3-2 standards.

The power supplies also meet EN55022 Level A specifications, achieved with a 212- microamp earth-leakage filter; in addition, lower-leakage filters down to 50 microamps are available. The series is also CE marked and approved to UL60950, CSA60950 and EN60950 standards.

The fan-cooled units measure a compact 2.5 x 7 x 11 inches and have a combination of screw or fast-on terminals for quick and easy installation.
