M 8261 & M 8263 Power Supplies
Operation:
These compact bench power supplies incorporate the latest switchmode technology and
delivers regulated output between 9 and 15V. Maximum current for M 8261 is 20A, whilst the
M 8263 delivers 30A. Includes combination volt and amp meter. Voltage output is adjusted via
the front panel control. Binding posts are provided for load connection. Fitted with cooling fan.
Figure 1:
1. Power switch: turns unit on and off
2. Noise off-set control: adjust this to eliminate the pulse noise of the switching power
supply. This function is designed for communications equipment.
3. Voltage adjustment: adjusts voltage between 9.0 and 15.0 volts. Turn clockwise to
increase and counter clockwise to decrease the voltage. At the centre position, voltage will
be 13.8.
4. Meter: displays the voltage or current.
5. Output control switch: set this switch to the “adjust” setting for variable output voltage.
When set to “13.8” output will be fixed at 13.8V.
6. Meter switch: select the position to indicate voltage (V) or current (A).
7. Meter calibration: adjust the meter to the zero position.
8. Output terminal: red positive (+) and black negative (-)
9. Cooling fan
10. 240V mains connector (IEC)
11. Fuse: remove fuse cover. Always replace with M 205 (20x5mm) slow blow (time delay)
type fuse.
Cautions:
– Place unit in a dry and well ventilated area.
– If a short circuit occurs whilst in use, the unit will be protected by a short circuit
protection function. Turn the unit off, remove the cause of the short circuit and
switch power supply back on.
– Do not use the unit for devices that require high current input for start up, such as
motorised equipment.
– Do not use the unit to charge a car battery
WARNING
DO NOT BLOCK THE AIR CONVECTION SLOTS OR COOLING FAN. THESE
PREVENT OVER-HEATING.
