Rail Industry Component:
Behlman Electronics Inc.: DC-AC Square Wave Inverter for Railroad and Transit

The Behlman SQ300 series inverter supplies 120 VAC from a 12 VDC source for continuous or standby operation of railroad signal equipment. The input is a nominal 13.2V lead acid or nickel cadmium battery with low internal impedance. The output is a square wave with a fixed frequency, 60 Hz, 100 Hz or 250 Hz plus/minus 1 percent regardless of load, input voltage or temperature. The output voltage is proportional to the input voltage and the inverter has an overload capacity of 110 percent. The SQ300 can be shelf mounted on supplied rubber feet or plug board mounted with optional bracket.
