2-wire AC (electronic insert FEL61)

• Two-wire AC version
• Switches the load directly into the power supply circuit via an electronic switch; always connect in
series with a load
• Functional testing without level change
A functional test can be performed on the device using the test button on the electronic insert.
U = 19 to 253 V , 50 Hz/60 Hz
AC
Residual voltage when switched through: typically 12 V
Observe the following as per IEC/EN61010-1: Provide a suitable circuit breaker for the device,
and limit the current to 1 A, e. g. by installing a 1 A fuse (slow-blow) in the phase (not the
neutral conductor) of the supply circuit.
S ≤ 2 VA
Residual current when blocked: I ≤ 3.8 mA
The red LED flashes in the event of an overload or short-circuit. Check for an overload or short-
circuit every 5 s. The test is deactivated after 60 s.
• Load with a minimum holding power/rated power of 2.5 VA at 253 V (10 mA) or 0.5 VA at 24 V
(20 mA)
• Load with a maximum holding power/rated power of 89 VA at 253 V (350 mA) or 8.4 VA at
24 V (350 mA)
• With overload and short-circuit protection
• OK status: load on (switched through)
• Demand mode: load off (blocked)
• Alarm: load off (blocked)
Always connect an external load. The electronic insert has integrated short-circuit protection.
