AUTOMATIC ELECTRONIC PHASE SELECTOR PEF-301

PEF-301 universal automatic electronic phase switch is designed to supply industrial and household appliance single phase 220 – 230V/50Hz loads from three-phase four-wire mains 3×380+N with the purpose of maintaining uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains.

Depending on voltage presence and voltage quality on phases, the PEF-301 will automatically select the optimal phase and promptly switch the single phase load supply of any wattage to this phase:

Loads of wattage up to 3 kW (up to 16A) get power supply directly from PEF-301
When wattage exceeds 3 kW (16A), PEF-301 phase switch will control the magnetic contactors (MC) coils of corresponding wattage.

AUTOMATIC ELECTRONIC PHASE SELECTOR PEF-320

PEF-320 universal automatic electronic phase switch is designed to supply an industrial and domestic single phase 230 V, 50 Hz load from three-phase four-wire mains 3х400+N in order to maintain uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains.
According to the voltage presence and voltage quality on the phases, the PEF-320 will automatically select the optimum phase in limits range set by user and switch the single phase load supply to this phase. It is possible to connect to one of the phases of the electric generator and inverter. The maximum and minimum voltage limits are set by user.

THREE PHASE PROGRAMMABLE VOLTAGE MONITORING RELAY RNPP-302M

RNPP-302M numeric voltage monitoring relay is designed for protection of three phase loads against major type of mains faults, as:

RMS voltage reaching beyond admissible thresholds – over and under voltage
Phase loss or Single phasing
Phase sequence order violation or reverse phase sequence
Phase coincidence or shorting of two or more phases
Phase Imbalance or asymmetry
Contactor output side monitoring – full phase switching, contactor health

The device performs monitoring the main circuit parameters and de-energizes (trips) load when the parameters fall beyond specified boundaries.

THREE PHASE VOLTAGE MONITORING RELAY RNPP-301

RNPP-301 voltage monitoring relay is designed for protection of three-phase loads against major type of mains faults, as:
