Remote On/Off Parallel Operation
・This unit comes with an integral on/off circuit, see wiring ・This power supply can not be configured in parallel with
diagram below. another power supply.
・Unit DC output is disabled when control voltage is applied
to RC terminal in reference to –V terminal.
・If SW is open or control voltage E is: 0 < E < 4.5V then unit
output is enabled.
・If SW is closed and control voltage E is: 4.5VDC < E
< 6.5VDC then output is disabled, and no need for current
limiting resistor R.
・If SW is closed and control voltage E is: 6.5VDC < E
< 24.5VDC, then current limiting resistor R must be =
(E – (1.1 +1000x0.005))/0.005. For example if E = 24VDC,
R = (24-(1.1+5))/0.005 = 3.5kΩ
Ripple
・Maximum ripple voltage is measured using JEITA
measurement method prescribed in RC-9131C.
・If ripple noise becomes excessive due to line length,
connect an electrolytic capacitor(47μF) and film capacitor
(0.1μF) at load side as shown.
Series Operation
・This Daitron power supply unit is configurable in series
with another Daitron power supply (if it too is configurable
in Series) in order to increase DC voltage or to provide
both “+” and “–“ DC voltage.
・In these configurations the MAXIMUM current delivered to
the Load is limited to the maximum allowable from the
power supply with the lowest current rating.
・To increase VDC (PS1 + PS2) see configuration (1) below.
Example: If PS1 and PS2 are both 12VDC/30W each, then
configuration (1) will provide 24VDC/30W
・To provide both “+” and “–“ DC voltage to a load see
configuration (2) below. Example: If PS1 and PS2 are both
12VDC/30W each, then configuration (2) will provide +12VDC
to Load1 and -12VDC to Load2, with a maximum total wattage
of 30W for both loads combined.
The maximum ripple voltage in the standard specification is a value
measured using the specified measuring circuit in the anechoic
chamber under the JEITA measuring method (See the drawing).
When the load line is long, the ripple on the load edge may become
large unless a capacitor, such as an electrolytic capacitor or a film
capacitor is connected. The output ripple cannot be measured
accurately if the ground lead of the oscilloscope is too long.

4．
Connections
・Using twisted pairs for I/O and routing them separately from output load wire is ideal to minimize noise interference.
・For improved noise filtering, add lower value of electrolytic capacitor (Section 2-11, 47µF)
・Minimize length of output load wiring.
・Connect FG terminal with earth ground of system using power supply using minimal length possible.
・Recommended tightening torque for M4 terminal screws is 1.4Nm/1.03lbft
・To minimize noise interference, be sure to separate the output load line, remote control line, and remote sensing line from
the input line. Noise immunity can be also improved by twisting each line.
・Attaching a small volume electrolytic capacitor to the load end is also effective to eliminate noise.
・For safety and noise prevention, ensure a secure grounding connection from ground terminal to equipment enclosure using
appropriate wire size. Otherwise, it may cause electric shock.
・Recommended tightening torque for M4 I/O terminal screws: 1.4Nm
・Shut off the power, and carefully make connections for the remote sensing function. Incorrect wiring or poor connection could
cause malfunction.
・Be sure to use each terminal (pole) of the terminal block at 20A or less.
・For the loading current of 20A or larger, use two terminal poles at the same time.
5．
Troubleshooting
・Confirm input AC voltage to be within spec of 100-240VAC/50-60Hz.
・Confirm all input and output connections are in accordance with above.
・Check the output adjustment potentiometer. Sometimes output OVP function turns off the output power when the potentiometer
is adjusted too high.
・Please note that an excessive capacitive load can create over current situation.
・
Confirm remote on/off is getting the appropriate voltage for desired operation.
・Before suspecting a failure.
・Check if the rated input voltage is connected.
・Check if the input/output wiring is appropriate.
・Check if the wire material is not too thin.
・Check if a large-capacity capacitor is not connected to the load side.
・Check if the remote control is not active.
・Check if the accessory connector for CN501 is connected.
The accessory connector is required if the remote sensing function is not used.
・Check if forced air cooling by external fans is properly functioning.
