All specifications are subject to change without notice.
󱫀 Input Voltage Range
Input voltage range is single phase 85 - 265VAC (47 - 63Hz) or
120 - 370VDC. Input voltage which is out of specication may
cause unit damage. For cases where conformance to various
safety specs(IEC,UL,CSA,EN) are required, input voltage range
will be 100 - 240VAC(50/60Hz).
󱫂 Output Voltage Range
V.ADJ trimmer(VR51) that is nearly output connector can adjust
the output voltage within the range. Output voltage range is
within CME150 : ±10%, CME240P : -10％ +20% of nominal out-
put voltage. To turn the trimmer clockwise, the output voltage
will be increased. Note over voltage protection ( OVP ) function
may trigger if the output voltage is increased ex-cessively.
󱫄 Inrush Current
This model has used Power Thermistor to pro-tect the circuit
from Inrush Current. Please carefully select input switch and
fuse in cases of the high temperature and re-input the power.
󱫆 Over Voltage Protection (OVP)
The OVP function ( Inverter shut down method, manual reset
type ) is provided. OVP function operates within CME150:
115-135%, CME240P:125-145% of nominal output voltage.
When OVP triggers, the output will be shut down. The input
shall be removed for a few minutes, and then re-input for re-
covery of the output. OVP setting shall be xed and not to be
adjusted externally.
󱫈 Over Current Protection (OCP)
Constant current limiting, automatic recovery. OCP function
operates when the output current exceeds CME150:125%,
CME240P:205% of maximum output current of specication.
The output will be automatically recovered when the overload
condition is re-moved. Do not operate overload or dead short
conditions for more than 30 seconds, which could result in
damage or insulation failure.
󱫊 Output Ripple & Noise
The standard specication for maximum ripple value is mea-
sured according to measurement cir-cuit specied by JEITA-
RC9131. When load lines are longer, ripple becomes larger. In
this case, electrolytic capacitor, lm capacitor, etc., might be
necessary to use across the load terminal. The output ripple
cannot be measured accurately if the probe ground lead of os-
cilloscope is too long.
󱫌 Series Operation
For series operation, either method (A) or (B) is possible.
Method (A) Method (B)
󱫎 Parallel Operation
（A）
To increase the output current is not possible.
（B）
To use as Back-up Power Supply
1. Set power supply output voltage higher by the forward
voltage drop(VF) of diode.
2.Adjust the output voltage of each power supply to be the
same.
3.Use within the specications for output voltage and out-
put power.

󱫐 Peak Output Current
CME150
For CME150-24, relation with average output current and peak
output current must satisfy formulas below. Also operating
time at peak output is less than 10sec.
When using pulse load, audible noise can be heard from power
supply unit.
Ip : Peak output current (A)
Iav : Average output current
(Maximum output current of Specication (A))
Im : Average output current (A)

CME240P
For CME240P-24, the peak output current should satisfy the
conditions below:
(1) Should not exceed the rated peak current in the specications.
(2) Duty cycle of the peak output current should be ≤ 35%(at
input voltage < 95V : ≤ 20%), and operating time of peak
output current is less than 10 seconds. If the power supply
is oper-ated under convection cooling, and ambient ex-
ceeds 45°C, the following operating period for peak current
is recommended.
Ambient Temperature (°C) Peak current operating time

put current is dened as below:

tions (Io should be average load after derating at various
mounting and am-bient temperature) (A)

: ≤ 0.2 at input voltage < 95V, ≤ 0.35 at input voltage ≥ 95V)
is possible after establish of output voltage. Please avoid
peak current operation during startup.
󱫒 Isolation Test
Isolation resistance between output and FG ( chassis ) shall
be more than 100MΩ at 500VDC. For safety operation, voltage
setting of DC isolation tester must be done before the test. En-
sure that it is fully discharged after the test
Output - FG (chassis)
500VDC 100MΩ or more
󱫓 Withstand Voltage
This model is designed to withstand 4.0kVAC between input and
output, 2.0kVAC between in-put and FG (chassis), and 500VAC
between output and FG (chassis), each for 1 minute. When test-
ing withstand voltage, set current limit of withstand voltage test
equipment at 20mA (Output-FG (chassis) : 100mA ). The applied
voltage must be gradually increased from zero to testing value
and then gradually decreased for shut down. When timer is
used, the power sup-ply may be damaged by high impulse
voltage at timer switch on and off. Connect input and output
as follows.
Input - Output (dotted line) 4kVAC 1min. (20mA)
Input - FG (chassis)(solid line) 2kVAC 1min. (20mA)
Output - FG (chassis) 500VAC 1min. (100mA)

󱫂 Mounting Method
Please use the mounting hole as:
CME150 : 4 holes of φ3.5
CME240P : 5 holes of φ3.5
And insert the spacer (MAXφ8mm) of height over 8mm to lift
the unit. Also use all 4 mounting holes for the unit installation.
The vibration spec. is the value taken when the unit is raised
by 8mm spacers.
And allowable area by metal pieces is 9mm from each PCB
corners. Refer to gure below.
CME150
CME240P
When mounting this power supply into host equipment, please
leave 4mm minimum spacing between all parts of the PCB as-
sembly except solder side and the earthed chassis of the host
equipment.
For solder side, please leave 8mm minimum spacing.
Otherwise, the insulation of medical requirement and with-
stand will not be satised.

・
All specifications are subject to change without notice.
FG should be connected to the earth terminal of the apparatus.
If not, the conducted noise and output noise will increase. Wire FG
Metal spacer
Chassis (Conductor)
• The output load line and input line shall be separated and
twisted to improve noise sen-sitivity.
• Use all lines as thick and short as possible to make lower
impedance.
• Noise can be eliminated by attaching a capacitor to the load
terminals.
• For safety and EMI considerations, connect FG to ground
terminal of equipment where power supply is mounted on.
• Recommended screw torque is 0.49N･m (5kgf･cm).
• Select the wire materials to adapt the connector as follows.
INPUT : AWG#22-#18
OUTPUT : AWG#22-#18
5. Wiring Method
Refer to the following fuse rating and use high-braking capac-
ity fuse when selecting the external fuses that are to be used
on input line. Surge current flows when line turns on. There-
fore use slow-blow fuse or time-lug fuse. Do not use fast-blow
fuse. Fuse rating is specified by in-rush current value at line
turn-on. Do not select the fuse according to input current (rms.)
values under the actual load condition.
CME150 : 5.0A
CME240P : 6.3A
6. External Fuse Rating
Before concluding that this product is at fault, make the follow-
ing checks.
• Check if the rated input voltage is connected.
• Check if the wiring of input and output is correct.
• Check if the wire material is not too thin.
• Check if the output voltage control (V.ADJ) is properly ad-
justed.
• Check if the output current and output wattage is not over
specication.
• Audible noise can be heard during dynamic-load operation.
• Audible noise can be heard when input voltage waveform is
not sinusoidal wave.
