SWT100 Component Side
Input voltage range of SWT30, SWT40 and SWT100 is si-
ngle phase 85-265VAC (47-63Hz) or DC110-340V.
Input voltage range for SWT65 is 85-132VAC or 170-
265VAC. Do not switch input voltage from 85-132VAC
directly to 170-265VAC, as may cause power supply dam-
aged.
All output voltage are fixed type (CH1, CH2, CH3). It
cannot be adjusted.
The output voltage of all channel is stabilized when more
than minimum output current of CH1 (all model) and CH2
(only SWT30, 40).
OCP circuit with zener diode clamp system is built into CH1
output (+5V). Over 6V of nominal voltage will clamp the
output. If the output voltage is lowered to due to the over-
voltage application, the output will not resume. Replace-
ment of the power supply unit is necessary (for a fee).
OCP type is current limiting with automatic recovery. OCP
function operates when the output current exceeds OCP
specifications. The output automatically recovers when the
over current / shorted conditions is removed. The output
will be automatically recovered whtn the overload or dead
short condition is canceled. When OCP operates in any of
the outputs, the other outputs will also get lowered. Do not
operate in overload or dead short conditions for more than
30 seconds. It could result in damage.

Output
The standard specification for maximum ripple value is
measured according to measurement circuit specified by
JEITA-RC9131. When load lines are longer, ripple be-
comes larger. In this case, electrolytic capacitor, film ca-
pacitor, etc. might be necessary to use across the load ter-
minal. The output ripple cannot be measured accurately if
the probe ground lead of oscilloscope is too long.
This series uses power thermistor to protect the circuit
from inrush current. Please carefully select input switch
and fuse in cases of the high temperature and the power
re-input.
Output current of CH1(+5V) and CH2(+V) of SWT30, SWT
40 can cope with peak current loads. Specified maximum
output current and peak output current must satisfy formu-
las below. Allowable peak output operating duration is less
than 10 sec. Cycle should be more than 10ms and duty
should be ≦ 0.35. (τ≦10 seconds)
