Remote ATS Monitoring Systems Series 300 and Series 7000

The ASCO Power Manager is a microprocessor metering device specifically designed for transfer switch applications to provide real-time measurements of single and three phase power systems. It uses digital signal processing technology to measure voltage and phase currents which it uses to calculate real, reactive and apparent power and bi-directional energy.

All measurements are viewed locally or at a remote PC via PowerQuest^® or SITEWEB^TM products. It can also collect data for both normal and emergency positions using auxiliary contact inputs from the transfer switch. Eight digital input and four digital outputs available for customer use. The ASCO 5200 Series Power Manager is available with or without a stand alone NEMA 1 enclosure.

Direct voltage input for systems up to 600 Volts AC can be monitored without the use of external potential transformers (PTs). Measure 3 phase currents and a fourth current input is available for measuring current in the neutral conductor.
