SS 1300 POWER SUPPLY
WARNING: HIGH VOLTAGE
!
320 VDC potential and 1200 VAC peak-to-peak voltage
The power supply is aprimary switchmode unit, which means that the
electronic components conduct AC-line voltage.
The "earth-symbol" in the schematic diagram is at line potential,
also cooling-fins and inductors are at line potential.
Service and measurement of the power supply
1/ Please contact the Manufacturer, to' get more information, before
you do any service of the power supply.
2/ All warranty service is done exclusively by tho Manufacturer.
3/ Bearing personal security in mind, and to avoid short-circuit
during measurement, all instruments must be isolated with tjie help
of independent 1:1 isolation transformers.
4/ The switching time is very short (nano seconds), and the switch
period is 35 us. Acondition for correct measurement and service,
is the use of a100 MHz oscilloscope (for ex. Tektronix 2215
or better).
