Numeric Power Devices and Overload Relays

Product Details:

????-163 is designed to protect (disconnect) the equipment (load) connected to it in the following cases:
− exceeding the threshold value of the controlled parameter;
− deviation of the mains voltage from the set values;
− excess of the temperature of the contact group (85 °??).
????-163 can be used as:
− power consumption limiting relay;
− voltage relay;
− energy meter (indication of total, active, reactive power, current consumption and mains voltage).
????-163 is powered by the circuit that feeds the load. ????-163 displays the value of the parameters and the status of the relay using LED indicators and display.

Product Details:

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

OM-310 Numeric Power Management System is used for:

• Power Controlling (Management)
• 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)
