FEL51
Connection data (load)
• relay with minimum retaining energy > 2.5 VA at 253 V~
(10 mA), or > 0.5 VA at 24 V~ (20 mA)
•
Relays with a lower holding power/rated power can
be operated by means of an RC module connected
in parallel
• max. retaining energy of relay < 89 VA at 253 V~ or
8.4 VA at 24 V~
• voltage drop across FEL51 max. 12 V~
•
Residual current with blocked thyristor max. 3.8 mA
• Load switched directly into the power supply circuit via
the thyristor.
Transient (40 ms) max. 1.5 A, max. 375 VA at 253 V
or max. 36 VA at 24 V (not short-circuit proof)
• min. terminal voltage 19 V~ at FEL51 when blocked
FEL52
