Multi-Temperature-Controller KS 800
4.4 Supply voltage
KS 800 is designed for a supply voltage rating of 24V DC, range 18V to 30V, residual ripple 5%.
The supply voltage must comply with the conditions of protective low voltage (SELV) according to
IEC 364-4-41 [VDE 0100-410].
Power supply load by one KS 800:
8 controller outputs + 4 alarm outputs each with 0,07A 20,16W
plus controller consumption 5,50W
results in a max. overall load (at 24V) of approx. 25,60W
The supply voltage minus pole is connected via the two external terminals (1 and 18) of
connector J1.
The plus pole is connected via terminals 19 and 36 of connector J2.
The supply voltage must always be connected from both sides, in order to prevent overload of
the circuit tracks.
We recommend using rail-mounted terminals with built-in fuse.
When mounting several units side by side, supply from one side and subsequent passing on
to the following unit must be avoided!
4.5 Fuses
Each unit must be protected with a separate fuse (in rail-mounted terminal) 2A, medium-fast.
Unless the "PWR" LED is lit with the supply voltage applied (check external fuse and polarity!), the
unit is defective and must be returned to the manufacturer.
