GENERAL DESCRIPTION
The Model 666 is a device for converting AC current into a low level DC current signal. By inclusion in AC metering circuits, usually derived from current transformers, high AC currents can be transmitted as low level DC signals permitting long cable runs and low cost indicating meters or recorders. The burden on the AC circuit is reduced and AC coupling problems are eliminated.
The DC output is isolated from the input providing a high degree of safety. The output is short and open circuit proof and calibration is unaffected by line resistance changes. Current range can be set by simple means of slide switches using simple tools.OTHER TRANSDUCERS
Dewar Electronics manufacture a range of electrical measurement transducers including voltage, frequency and power transducers.
