| Series Features |
| LF-G SERIES RELAYS |
| Series Description: Panasonics LF-G Series Relays are non-polarized 1 Form A power Relays that can switch up to 33 amps at 250 volts AC. This series is offered with a 1.5 or 1.8-millimeter contact gap and comply with photovoltaic standards, making them ideal for AC line switching in solar applications as well as UPS, microwave ovens, battery charge, and discharge systems. To save energy, designer engineers can reduce the coil holding voltage to 35% of the nominal coil voltage, dropping the operating power to 170 milliwatts. These Relays have a compact size that allows for smaller, higher-density designs, and feature excellent creepage, clearance, and breakdown voltage to ensure safe operation. |
| Applications: Photovoltaic power generation systems (Solar inverter), Uninterruptible Power Supplies (UPS), Home appliances, Office equipment |
