The Power Electronics PT435-8 single-phase DIN-rail voltage monitor checks the mains voltage and protects single-phase loads from overvoltage and undervoltage. The undervoltage protection is adjustable from 170–215 VAC, while the overvoltage threshold is preset to approximately 250 VAC. It also detects total loss of phase or neutral: the relay energizes when the voltage is within the adjustable threshold and de-energizes if the threshold is exceeded or there is a total loss of phase or neutral.
The monitor operates at 230 VAC and 50 Hz. It features a relay with one changeover contact and LED indicators for power and relay activation.
