Sontay has added a new highly programmable multi-function kWh Meter to its comprehensive range. The new PM M850 has user programmable CT and VT ratios and can be used on any single or 3-phase system.
Sontay’s new PM-M850 is a simple to use digital, universal kWh meter and can perform all operations including programming by using the four push buttons on the front of the unit. The unit is capable of measuring 16 parameters to include voltages, currents and frequencies as well as energy and power, all of which can be displayed on the unique blue LED screen which can be easily read, even in direct sunlight.
In addition, outputs are available as either a pulsed output for kWh or VAr, or an RS-485 2-wire Modbus output for all the parameters measured. The meter can be used in a range of applications including single phase; single phase 3-wire; 3-phase, 3-wire unbalanced load; and 3-phase, 4-wire unbalanced load. The new PM-M850 multi-function kWh meter also features 5A CT secondary current.
