Specifications Parameter Specification Product Line WATSN Automatic Transfer Switch Rated Current (Ie) 32 A (per pole) Number of Poles 4 Poles (3P + N) - Transfers all three phases and the neutral Switching Elements Two electrically and mechanically interlocked contactors (for this current rating) or switching devices. Rated Voltage (Ue) Typically 230/400V AC, 50/60 Hz Control Power Supply Typically AC/DC, specific voltage range defined by the "V" in AVK (e.g., 24V DC, 110V AC, 220V AC). Transition Type Open Transition (Break-Before-Make) - Standard for this model. One source is completely disconnected before connecting the other, causing a brief power interruption (typically < 100ms). Control Features (AVK Logic) • Automatic Operation: Monitors both sources and transfers based on pre-set priorities and conditions (e.g., Main failure → start Gen → transfer to Gen). • Programmable Delays: Start-up delay for generator, cool-down delay, transfer delays. • Return to Normal: Automatic retransfer to the preferred source (Main) once it is restored and stable. • Voltage & Frequency Monitoring. Operation Modes Auto / Manual / Off selector switch. Enclosure Compact, enclosed unit suitable for DIN rail or panel mounting. IP rating typically IP20 or higher. Standards IEC 60947-6-1, relevant safety standards.
