Power Supply Adds Voltage Alarm Contacts

The company’s Series A and B power supplies (with outputs from 5 to 125 Vdc) are now available with optional contacts for controlling an external audible or visual alarm, or to signal a computer. The contacts switch if the power supply’s output voltage deviates by 2V or more from its nominal rating. Because the contacts are SPDT, both an alarm and a normal-operation indicator can be controlled. Price for the option is $35. ACOPIAN, Easton, PA. (800) 523-9478.
