Acoustical noise

Specifications 19

Acoustical noise

The rectifier does not produce sound levels above 60 dB with "A" weighting measured 1.5 m (5 ft.) above the floor and 0.5 m (2 ft.) from the rectifier, while operating at no load, partial load, or full load.

Efficiency and power factor

Efficiency is 88% at nominal input voltage of 208 V and maximum output load of 25 A at 54 V DC.

Power factor is 0.60 at a nominal voltage of 208 V AC and a maximum load of 25 A with 0.5 ohm line impedance.

Reliability

The rectifier has a mean time between failures (MTBF) greater than 120,000 hours (Bellcore spec. TR-NWT-000057) under normal operating conditions, at 30°C.

Heat dissipation

The maximum heat dissipation is 150 W at -56 V and 25 A load (1 x MPR25).

Electromagnetic Interference (EMI)

The rectifier meets FCC part 15, sub-part B for Class A digital devices.

Environmental

Operating

A two- inch airflow clearance is required at the front and rear of the rectifier. Consult Astec for applications requiring less than a two-inch clearance.

The rectifier will operate satisfactorily under the following environmental conditions:
