PEF-320
NOVATEK-ELECTRO
If the temperature of the device after transportation or storage differs from the ambient temperature at which it is
supposed to be operated, then before connecting to the mains keep the device under the operating conditions
within two hours (because of condensation may be on the device elements).
ATTENTION! The device is not intended for operation in the following conditions:
–
Significant vibration and shocks;
–
High humidity;
–
Aggressive environment with content in the air of acids, alkalis, etc., as well as severe contaminations
(grease, oil, dust, etc.).

3. DESIGN AND PRINCIPLE OF OPERATION
The electronic phase switch PEF-320 is a microprocessor-based digital device.
The user should make settings of the trip threshold limits of the PEF-320 - the minimum and maximum
voltage values at which the device trips and switches over to the backup phase (switches off the load).
The glow of one of the green LEDs L1, L2, L3 on the front panel indicates the phase to which the load is
connected.
PEF-320 has three independent inputs, terminal L1 (priority phase) and L2, L3 (backup phases).
