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
. V
oltage output is adjusted via
the front panel control. Binding posts are provided for load connection. Fitted with cooling fan.

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

. 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. T
u
rn the unit off, remove the cause of the short circuit and
switch power supply back on.
–
D
o not use the unit for devices that require high current input for start up, such as
motorised equipment.
–
D
o not use the unit to charge a car battery
