The SKAD01 voltage monitor relay mounts on a standard DIN rail and continuously monitors single-phase 220VAC supply. When the measured voltage exceeds the adjustable overvoltage threshold (230–300V) or falls below the adjustable undervoltage threshold (150–210V), the relay trips after a configurable delay of 0.1–20 seconds to protect connected equipment.

The compact 22.5×58×90mm (W×D×H) plastic enclosure fits standard distribution boards. Error indication signals a fault condition, and CE marking confirms compliance with European safety standards.

Key Features

• Adjustable overvoltage protection threshold: 230–300V
• Adjustable undervoltage (voltage-drop) protection threshold: 150–210V
• Configurable trip delay: 0.1–20 seconds
• Single-pole (1P) DIN-rail mounting, 22.5mm wide
• Error indication for fault signalling
• Operating frequency: 50/60Hz

Product Benefits

• Adjustable thresholds allow the relay to be tuned for the specific tolerance of the connected network
• Configurable delay prevents nuisance tripping from brief transient fluctuations
• DIN-rail form factor integrates directly into existing distribution boards without additional hardware
• Error indication enables rapid fault diagnosis at the panel
• Wide supply voltage tolerance (220VAC ±35%) accommodates unstable grid conditions
