Technical description

Operating voltage U
B
The max. operating voltage of the SSRPC is approx. DC 60 V. The
min. operating voltage required for 24 V solenoids depends on the
overall ohmic resistance in the load circuit. The switch-on current is
reduced by:
- the voltage drop on the load cable
- the load resistance increasing with the operating temperature of
the load.

3 A 2x50 m/2x100 m/2x200 m/2x300 m
The load capacity is no longer ensured when the minimum operating
voltage falls below U

and the output will be switched off. Only when an operating voltage
of 29.4 V is exceeded will the load be switched on again and normal
operation status is restored.

falls below 57 V will the load be switched on again and normal opera-
tion status is restored.
Switch-on current I

The output transistor connects the operating voltage to the inductive
load until actual switch-on of the solenoid (pickup current). After this
period the load current is set back to holding current I

Technical description
Rated current I
The current rating of the applicable load at its rated voltage should
be set between 0.1...3.1 A. The holding current of the load is internally
adjusted to 60 % of the set current rating. This holding current can
be measured by means of a voltmeter connected to the 2 mm current
measuring plugs (current-proportional voltage: 1 V = 1 A).

Setting the current rating (adjustable between 0.1...3.1 A)
The current rating is set by means of a rotary switch (switch setting
0 A - 1 A - 2 A) and a 270° potentiometer (setting range between
0.1...1.1 A). The sum of the two settings should equal the current
rating of the load.
Example: 24 V load with I
Setting: switch 1 A + potentiometer 0.5 A

The load is disconnected only after approx. 15 sec if the current rating

value is not corrected and the red LED will be permanently lighted.
Reset is only possible by switching on again.
The tolerance range, in which faulty setting will not be indicated, is
approx. ± 30 % of the holding current.
