Indicators/Signal Outputs
• Minor injury due to electric shock may occasionally occur. Do not
touch the terminals while power is being supplied. The voltage may
be applied even if the INPUT OK indicator does not light. Be sure
to check the input voltage when performing wiring.
• The output voltage may be generated even if the DC OK indicator
does not light. Be sure to check the output voltage when
connecting to the load device.
• This function monitors the voltage at the power output terminals.
To check the voltage accurately, measure the voltage at the load
end.
• If the output voltage is set to less than 90% of the rated output
voltage, the DC OK indicator may go off and the DC OK signal
output may be turned OFF.
• The Iout > 100% Indicator may light up, and the Iout > 100% Signal
Output may turn ON during peak current operation, however, the
Power Supply can be used as long as the operating conditions
specified in
Peak current
(P.14) are satisfied.
• During a short-circuit, the indicator will operate intermittently due to
the overload protection function. When this happens, the Iout >
100% indicator will blink in accordance with the intermittent
operation, and the Iout > 100% signal output will repeatedly turn
ON and OFF. The shortest ON time of the Iout > 100% signal
output during intermittent operation is 5 ms.
Peak current
The boost current is a temporary current that exceeds the rated
current.
However, it should meet the following four boost current conditions.
• Time that the boost current flows: t1
≤
10 s
• The boost current: Ip
≤
Maximum boost current
• The average output current: Iave
≤
Rated output current
• The time ratio of the boost current flow: Duty
≤
30%
• Do not allow the peak current to continue for more than 10
seconds. Do not allow the duty to exceed 30%. The Power Supply
may be damaged.
• Ensure that the average current of one cycle of the boost current does
not exceed the specified value. The product may be damaged.
• Derate the load at the boost current and average output current
according to the ambient operating temperature and mounting.
Charging a Battery
If you connect a battery as the load, install overcurrent control and
overvoltage protection circuits.
Output voltage adjuster (V.ADJ)
• The output voltage adjuster (V.ADJ.) may possibly become
damaged. Do not apply more than the required force.
• After completing output voltage adjustment, be sure that the output
power or output current does not exceed the rated output electric
power or rated output current.
Series Operation
Two Power Supplies can be connected in series.
Note: 1.
If the load is short-circuited, a reverse voltage will be
generated inside the Power Supply. If this occurs the
product may possibly deteriorate or be damaged. Always
connect a diode as shown in the figure. Select diodes with
the following ratings.
2.
Though Power Supplies having different specifications can
be connected in series, the current flowing through the load
must not exceed the smaller rated output current.
Be sure to check that the Iout > 100% indicator is not lit or
the Iout > 100% signal output is turned OFF before using.
