16.02.2012 B&K Precision’s new model 1657 AC power source offers users 1500 VA of power with programmable AC voltage up to 270 VAC and adjustable frequency from 45 Hz to 450 Hz. The 1657 comes in a standard 19” rack-mountable design and provides a universal line output terminal. This AC power source is an ideal solution for industrial product testing applications, allowing users to perform input voltage margin testing at 50 and 60 Hz, including avionics testing where equipment is operated at the 400 Hz range. Setting voltage and frequency parameters is made simple with the front panel’s easy-to-use control knob. The 1657’s bright VFD display continuously monitors the voltage, current, frequency, and power with a 0.1 V / 0.01 A / 0.01 Hz / 1 W resolution. Also included is an RS232 interface for remote control.
