MODEL 5425

The Columbia Model 5425 is a four channel, constant current power supply that is specifically designed to be used with Constant Current Mode Transducers and electronics. The output current to the transducer is set to 3.0 mA DC nominal. Individual inputs and outputs are made through 10-32 and BNC connectors located on the rear panel. This instrument's output is AC coupled so that the output is an AC signal with the bias voltage removed. In addition to individual channel outputs, a NBC monitor jack has been provided on the front panel. Any channel's output can be monitored by the use of the rotary "Channel Select" switch. This allows the user a convenient means of monitoring and channel with a single instrument. For each channel, there is a LED that indicates when a transducer is connected. If for any reason the cable breaks or, the transducer is disconnected and the indicator will turn off. The Model 5425 is designed to operate using three 9-volt alkaline batteries.
