Relays and timers ELVERT RF, RV, RD, RT, etc.

RP pulse relays are designed to control the load from several locations along a two-wire line using parallel-connected push-button switches when organizing lighting of passageways, corridors, staircases, etc. (switching on at the entrance, switching off at the exit).

• Pulse relays RP. Technical specifications.

RT time relays are designed for automatic switching on/off for a given time of household and industrial appliances and electrical installations. Various versions according to the time delay adjustment range and the type of functions – on/off delay, power off delay, multifunctional relays with a wide range of functions (from 10 to 24 functions), relays for star-triangle switching, digital relays with cyclic programs (astronomical, weekly, annual).

• RT time relay. Technical specifications.

RD temperature control relays are designed for automatic switching on and off of heating or cooling equipment in order to maintain a set air temperature in residential and industrial premises, as well as temperature control of various kinds of liquids in technological processes.

• RD temperature control relay. Technical specifications.

RF phase control relays are designed to protect electric motors and electrical installations powered by a three-phase network in cases of: absence of at least one of the phases, phase asymmetry in voltage (only for the RF-3ZC model), violation of the phase sequence.

• RF phase control relay. Technical specifications.

Single-phase RV voltage relays are designed to monitor the voltage in a single-phase AC circuit and protect household and industrial electrical installations from high and low voltages, connected to a single-phase load circuit break. There are 2 models in the line – with RV-1U voltage indication and control and RV-1IU current and voltage indication and control.

• Voltage relays are single-phase pass-through RV. Technical specifications.

Three-phase RV voltage relays are designed to control the voltage in a three-phase alternating current circuit and protect electrical installations from high and low voltages, breakage of one of the phases of the circuit, phase sequence violations, phase asymmetry in voltage. The line includes simple models with actuation regulators on the front panel, as well as a digital model RV-3ZG equipped with an LCD display.

• Voltage relays are three-phase RV. Technical specifications.

RC current relays are designed to protect transformer substations and power lines with a voltage of 400 V from single-phase short circuits, as well as for use in relay protection and automation systems as a device that responds to the deviation of the AC power in the controlled circuit from the set value.

• RC current relay. Technical specifications.

Liquid level switches RL are designed to control and maintain a preset level of conductive liquids in tanks, pools, water towers, etc. and control electric motors of pumping units.

• Liquid level relay RL. Technical specifications.

RTE timers. The line has a simple staircase timer for automatically turning off lighting on stairwells, corridors, etc. after a specified period of time after switching on, as well as a digital timer for automatic load control according to the established weekly program.

• RTE timers. Technical specifications.

RPH photo relays are designed to automatically turn on the load at dusk and off at dawn when organizing street lighting, shop windows, billboards, etc., as well as in industrial and household automation devices.

• RPH photo relay. Technical specifications.
