The max. admissible operating voltage of the SSRPC is approx. DC 60 V.
The min. operating voltage is a function of 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.

The load capacity is no longer ensured when the minimum operating
voltage is under limits. The RED LED (fault) will indicate and the
circuit breaker will trip after approx. 15 s.

Technical description
Rated current I

hold current
I
H
The current rating of the applicable load at its rated voltage should be
set between 0.1 and 3.1 A.
The hold current of the load is internally adjusted to 60 % of the set
current rating. This hold current should be measured by means of a
voltmeter connected to the 2 mm current measuring terminals (0.1
shunt).
G
Operating voltage (terminals 1 and 2):
reverse polarity protected by means of a relay.
The relay will only pick up and apply voltage to the device if the
operating voltage is correctly polarised. This relay will then remain
permanently energized, without being influenced by the control
input.
G
Control circuit (terminals 6 and 7):
reverse polarity protected by means of a diode.
G
Auxiliary voltage status outputs (terminals 10 and 5):
reverse polarity protected by means of a diode.
G
The load output (terminals 3-4) or the inductive load must not be
fitted with a free-wheeling diode as the free-wheeling current is
controlled electronically. This control also causes a very short fall
time of the inductive load.
The solenoid connector may be provided with means of visual
indication (LED).
Switch-on current
To reach the max. inrush current the output transistor connects the
operating voltage to the inductive load for approx. 400 ms. After this
period the load current is set back to hold current.
Setting the current rating
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
and 1.1 A).
The sum of the two settings should equal the current rating of the
load.
Example:
24 V load with I
= 1.1 A
Setting:
switch 0 A + potentiometer 1.1 A, or
switch 1 A + potentiometer 0.1 A
