Numeric Power Devices and Overload Relays

We are offering Numeric Motor Protection Device for Two Stage Winding. Specially designed for continuous monitoring of motors having dual windings. Thisdevice monitorsthree phase equipment operation parameters: mains voltage, phase/line RMS currents, wattage, positive and negative sequence voltages and currents, isolation resistance to frame, differential ground leak currents (zero sequence currents), temperature operation modes.

Product Details:

Voltage TypeAC
Voltage (V)220 - 240V
Number of Poles2 Pole
Current (Amps)0 - 100A

RMT-101 current overload/over current relay is used for load rejection in case the current exceeds the set value between 0 and 100 amperes.

The device can be used in the following capacities :

  • Digital ammeter
  • Current consumption limiting relay
  • Priority load selection relay

LEDs on the front panel of the relay indicate :

  • Load state (on/off)
  • Exceeding the maximum allowed load current threshold

Depending on the work mode, the three digit seven-segment indicator indicates:

  • Actual load current value
  • Maximum current value after the last reset
  • Value of the parameter being set
  • Time remaining until load activation or rejection
  • Presence of a reclosing blockage

Regulating potentiometers allow the user to set the following values:

  • Maximum allowed load current value threshold
  • Time for load rejection in case of exceeding
  • Maximum allowed load current threshold
  • Time delay before load activation after the current returns to the allowed level

Product Details:

Voltage TypeAC
Voltage (V)415 V
Number of Poles3 Pole, 4 Pole
Current (Amps)800A

OM-310 Numeric Power Management System is used for:

  • Demand Controlling
  • Generator protection
  • Overcurrent protection
  • Earth leakage protection
  • Voltage monitoring
  • Complete load rejection when the power consumption exceeds the main threshold for a user-set time
  • Partial load rejection when the power consumption exceeds the main threshold for a user-set time
  • Measurement and indication of three-phase electric circut parameters (active values of phase and line voltages)
  • Positive, negative and zero phase sequence voltages; active phase current values; active, reactive and full power load consumption, power factor
  • Emergency signaling
  • Remote load activation and rejection via the RS-232/RS485 interface or external switch

The device allows working with a load of 2.5 – 30 kW with the use of integrated current transformers, and with a load of up to 350 kW with the use of external current transformers, including in networks with an insulated neutral.

We offers the consumer the following protection types:

  • Low-quality network voltage (unacceptable power surges, phase breaks, phase sequence disruption, phase/line voltage distortion)
  • Current exceeding the maximum allowed value on any of the load phases
  • Ground leakage currents
  • Automated reclosing can be allowed or forbidden for each type of protection
  • Electric equipment is protected by means of controlling the magnetic starter coil (contactor)

Product Details:

Voltage TypeAC
Voltage (V)240 V
Current (Amps)8A
Number of Poles2 Pole
ApplicationPower limitting relay, Power Display

OM-110 power limiting relay is used for continuous control of single phase active or total power. The measured power range is between 0 and 20 kW or between 0 and 20 kVA OM-110 rejects the load in case the user-set maximum allowed load consumption power level is exceeded (with a set rejection time), and subsequently activates the load automatically (with a set activation delay time, or an option to block reclosing).

 

Potentiometers and DIP-switches installed in the front panel allow the user to set the following values:

 

  • Maximum allowed power level
  • Relay activation time
  • Automatic reclosing delay time

 

The load consumption is measured without electrical opening, using an integrated current sensor.

 

OM-110 relay can be used in the following capacities:

 

  • Digital wattmeter (active or full power meter)
  • Load consumption limiting relay
  • OM-110 is powered by the voltage measuring circuits
