High-power relays R50A and R90A
High-power relays R50A and R90A
The R50A and R90A high-current relays are designed for applications in photovoltaic systems, solar inverters, AC chargers, power supplies and UPS systems. These relays provide reliable operation, high durability. They are suitable for PCB mounting. They are relays with high switching current, large contact gap and insulation class F: 155 °C. The coil holding voltage of these relays can be reduced to 50-75% of the rated coil voltage, providing exceptional energy savings.
