USER'S MANUAL FA-405
PROGRAMMABLE POWER SUPPLY

1. GENERAL

1.1 Description

The FA-405 is a programmable switching power supply with backlight liquid crystal
display built to the latest technological standards.
With its continuously adjustable voltage and current settings, this power supply can
be used universally in school, work, hobby, and other applications. An electronic current
limiter protects the power supply from overload and short-circuits at its output; a fan
controlled by a temperature circuit protects the power supply (its electronics) from
thermal overload.
During such an overload (short circuit or overload) the output is regulated down, i.e.
the voltage is reduced. Only when the short-circuit has been remedied is the output
released.
The set values can be read via the illuminated multiple-line LCD display. The
voltage, current or power setting is adjusted by means of an encoder wheel in 10mV,
1V, 10mA, 0.1A and 1 W steps respectively. Therefore the exact adjustment of the
output voltage and the current limit and maximum output power is possible.
Construction is in accordance with VDE 0411 = EN 61010. Moreover, the FA-405
has been EMV-tested and fulfils the requirements of the applicable European and
national directives.
To maintain this condition and to guarantee safe operation, the user must observe
these operating instructions without fail.
