DESCRIPTION

The Teledyne Relays 3PAK220 relay is a 3-phase, 250 Vac solid-state relay with status indication. It delivers 28 Vdc input and .A output. Relay inputs and outputs are optically isolated. The relay is a commercial-off-the-shelf (COTS) relay designed for 3-phase, 47–440 Hz applications where low EMI and reliable operation under conditions of severe environmental stress are a requirement. Electromagnetic interference compliant per the requirements of MIL-STD-46 and MIL-STD-462. This relay component passes “in-system” EMI testing for conducted emissions per test methods CE0, CD02 and CE04; for conducted susceptability per CS0, CS02 and CS06; and for radiated susceptability per RS02 and RS03.
