The APT-TH Series Power Transducers monitor watt consumption of three phase loads.  They provide an analog signal proportional to the active power consumed by the monitored load. 

The three current carrying conductors pass through the three windows of the top section and the matching voltage input at the terminals.  The AP-TH is a one-piece solution for measuring power; no external current transformers are needed and installation is easy. 

The design of the APT-TH ensures that the monitor is always correctly orientated.  If connected improperly by mismatching the current and voltage inputs, or placing a conductor through the sensing window back to front rather than front to back, the LED will change colour from green to amber.  The LED will also turn amber if the phase A conductor is placed through the phase B sensing window, or if power factor is lower than 0.50.

Power Transducer Applications:

• Pump Monitoring - Monitoring pumps to detect open intake of outflow lines, cavitation or failing bearings.
• Grinding and Milling -  Measure wattage/horsepower to optimize feed rate.  Detect broken or missing tools or drill bits. Detect when the tool contacts the material.
• Equipment Monitoring -  Constant output proportional to wattage consumed can be compared with utility bills, providing a cost per hour or cost per operation of a machine or process.

Power Transducer Features:

• One-piece Solution – no external current transformers.  No chance of loose CT secondary provides added safety.
• Easy Installation -  Snaps onto DIN rail or can be panel mounted using screws.
• Finger Safe Terminals for Safety – LED indicator.  LED on base shows correct phase relationship match.  Green for normal operation and orange for incorrect installation.
• Three Ample Sensing Windows – Wire carrying 200A fits easily.

Designed to meet UL, cUL and CE -  Accepted worldwide. 

For loads 0.5kW – 200kW.
