Optionally, instead of RS 232 interface, a connector may be fitted on the rear panel to connect an
analogue interface. In the bottom and top cover of the steel case are created slots for an air intake.
This slots are covered by a fine net. Cooling air passes along heat sinks and goes out through a rear
panel. Efficient cooling needs following an unobstructed area between:
- a table and bottom cover
- min. 15 mm
- stacking of two units
- min. 20 mm
- a rear panel of the unit and a wall - min. 100 mm
OPERATING INSTRUCTIONS
Power Supplies SPS 1000 series of class I equipment should normally be connected via a 3 line cable
to mains PH+N+PE 50Hz, 230V
±
10%/TN-S. Protection achieved by basic insulation and
connection to earth for all conductive parts that are capable of assuming hazardous voltage if the
basic isolation fails. An output secondary circuit with voltages between conductors and between any
conductor and earth, not exceeding 100V DC (basic enviroment), under normal operating conditions,
which is separated from hazardous voltage by at least basic insulation, and which meets neither the
requirements for an SELV circuit nor the requirements for a limited current circuit.
Between output and input circuit (main and auxiliary transformers) is used reinforced insulation and
creepage and clearance distance is 8mm. Based on above mentioned Power Supplies SPS 1000 series
appear to be a safety equipment.
Handling and operation of the SPS 1000 is very simple.
