Field Tools Loop Power

The Field Tools Loop Power provides portable power to loop-powered 2-wire transmitters for commissioning and testing. It's a fully contained power source that takes the low voltage from three "AAA" alkaline batteries and increases it to a highly filtered 24 volt power source. Loop Power is easy to use, includes all connection leads, and makes it simple to attach your HART protocol modem to the loop.

The voltage conversion is done using a high efficiency switching DC-DC converter to maximize battery life - over 6 hours at 12mA. "Quick simple power for transmitter field calibrations and testing." Connecting is quick and simple. Clip on the two mini-grabber clips to the power input of your transmitter and push the connect button. A single connect/disconnect button enables or disables the 24 volt output while a status LED indicates
