General description
The DC-power supply t
ype
EPS/HC 40030-60
is a sophisticated
switch m
ode type rectifier, designed for the industry. It is
designed to fit in a 19”- casing.
The control of the output parameters is done by keys in the front panel of
the unit (internal setpoints mode) or via external analog set signals
(external setpoints mode). The output values are shown on the large,
illuminated display. The display can also show status and warning or
error messages.
The electronic regulation guarantees correct output parameters during
the operation, even with variable loads at the DC output.
Over temperature protection
The device is temperature protected. In case of rising interior
temperature, first the fan speed increases. If the temperature is still
increasing, the device decreases the output current automatically;
in extreme case, the output is set to zero. After a cooling phase, the
output power is increased automatically.
Attention:
Auto-re-start after cooling down!
Do not run the power supply at higher environmental temperatures
than 35°C!
2.1
Switch mode technology
This device was designed as switch mode type DC power supply. The
advantages of the switch mode technology are:
- very compact design
- maximum regulation accuracy
- very low ripple
- high efficiency; power factor cos.
0.95
2.2
PFC technology
The PFC technology (Power Factor Control) allows a reduced phase
current by increasing the efficiency of the power part.
