These digital meter set point relay for voltage (type MRD-V) are accurate and are characterized by steady bright 7-segments 12.7 mm LED display. Our digital meter set point relay for voltage (type MRD-V) are available in compact size of 96 x 96 x 150 mm. Normally available for range of 0 600V AC, the digital voltmeter set point relays are also available for ranges from 0-200mV, 0-200V, direct reading DC or AC. These digital meters set point relay for voltage (type MRD-V) are also available for PT operated HT applications in ranges of 3.3KV, 6.6KV, 33KV, 66KV, 132KV and 220KV. Ripple integration provided in DC meters gives stable display for bridge rectified power supplies.

These digital meter set point relay for current (type MRD- A) are accurate and are characterized by steady bright 7-segment 12.7mm LED display and are available in compact size of 96x96x150mm. Normally these digital meter set point relay for current (type MRD- A) available for CT operated AC application, the Ammeter is also available for ranges of 0-2mA, 0-20mA, 0-2mps and 0-5Amps, direct reading DC or AC. These digital meter set point relay for current (type MRD- A) are very successfully used as Demand Controllers at a fraction of the cost of other so called Maximum Demand Controllers that provide a lot of unnecessary features to increase the cost.

These digital meter set point relay for frequency (type MRD-F) are accurate and are characterized by steady bright 7-segment 12.7mm LED display and are available in compact size of 96x96x150mm. These digital meter set point relay for frequency (type MRD-F) is designed to accept wide-ranging voltage input from 50V to 600V. These digital meter set point relay for frequency (type MRD-F) are available for the mains frequency range of 45.0-55.0Hz, the display is exceptionally steady compared to some other makes of frequency meter that are based on counting circuits. The Syntron digital meter set point relay for frequency (type MRD-F) is based on a built in frequency to voltage transducer. The output of the transducer being integrated for conversion to digital is steady, and accurate.

These digital meter set point relay for W, KW and MW (type MRD1P1EW, MRD3P2EW, MRD3P3EW) are accurate and are characterized by steady bright 7-segemnt 12.7mm LED display and are available in compact size of 96x96x150mm. Time shared four-quadrant multiplier technology is used for true RMS, accurate measurement at all power factor. The digital meter set point relay for W, KW and MW (type MRD1P1EW, MRD3P2EW, MRD3P3EW) are available in single-phase single element (type MRD1P1EW), three phase double element (type MRD3P2EW) and three phase triple element (type MRD3P3EW) versions, for LT as well as HT applications. These instruments are very successfully used as Demand Controllers at a fraction of the cost of other so called Maximum Demand Controllers that provide a lot of unnecessary features to increase the cost.

These digital meter set point relay for var, Kvar and Mvar (type MRD3P2VAR) are accurate and are characterized by steady bright 7-segement 12.7mm LED display and are available in compact size 96x96x150mm. Time shared four-quadrant multiplier technology is use for true RMS, accurate measurement at all power factor. The digital meter set point relay for var, Kvar and Mvar (type MRD3P2VAR) are available in three phase double element version only (type MRD3P2VAR). The instrument are available for LT as well as HT applications.

These power factor alarm relay (type MRD-PF) are accurate and are characterized by steady bright 7-segment 12.7mm LED display and are available in compact size of 96 x 96 x 60mm. The power factor alarm relay (type MRD-PF) is designed for application in manually controlled power factor improvement systems. Microcontroller based, the instrument provides accurate measurement of power factor (cos x) and a display of three-and-a-half digits from 0.000 to 1.000.separate indications by LEDs are provided for lag and lead. Alarm limits are factory programmed. Standard version has lag setting of 0.96 and lead setting of 0.99. Time delays of 10 seconds are programmed into the standard version for lag as well as lead. Two relays are provided inside one one for lag and the other for lead. The lag relay operates when the power factor goes lagging and below the lag setting, for the programmed time. Similarly for the lead relay.
