Model# PTB

Multiple Output AC Power Transducer

Our Multiple Output PTB Current Transducer is designed to measure and provide analog output signals for all parameters of voltage & current. Optional outputs for power factor, apparent power “VA” and watthours are available as plug-in circuit cards.

The 10.75″ X 8.9″ X 2.5″ circuit board is provided with mounting holes to fit a 10″ X 12″ NEMA case or the circuit board can be mounted in the user’s cabinet with the stand offs provided. Input and output terminals are located directly on the circuit board.

All of the electronics circuitry uses solid state multipliers, RMS converters and amplifier. The unit requires 115Vac instrument power. (Optional 220VAC is available)

The unit is calibrated at the factory using standards traceable to NIST.
