INTELLIGENT BUILDINGS/// POWER PCB RELAY PCFN SOLAR

TE Connectivity has expanded the PCFN Solar Relay line to include

a new high performance relay with larger ( > 1.8 mm) contact gaps

to support extended insulation requirements for use in photovoltaic

applications. With the same mechanical dimensions as the standard

PCFN solar relays, the new high performance version has increased

thermal performance up to 90°C and features a 1.5 W coil with low

holding power of 200 mW to help lower energy costs.
