■ Standard usage instructions
The CHVM series does not basically require additional parts, but add capacitor C1 to the input terminal if input
impedance is high due to a long distance between the power supply and converter, an input line is thin, a filter is
inserted on the input side, etc. When fitting a capacitor, try to add on the converter terminal side so as to reduce
lead inductance.

■ ON/OFF Control
Output voltage can be turned ON/OFF by closing/opening between the ON/OFF terminal and Vin terminal.
Between ON/OFF terminal (5) and Vin terminal (2)
(1) Output OFF when opened
(2) Output ON when shortcircuited (0  0.4V, 1mA max.)
As the ON/OFF terminal is pulled up to +Vin inside the power supply, pay attention to the voltage of elements
(photocoupler, transistor, etc.) to switch the ON/OFF terminal.
Shortcircuit when ON/OFF is not controlled.
Ensure that there is no chattering to the ON/OFF terminal which affects output voltage. Output residual voltage is
0.5% or less when output is OFF under ON/OFF control (at the rated inputoutput).
■ Over current protection
The CHVM series has a builtin over current protection circuit against overload and load shortcircuit. The circuit
reduces output voltage in case of overload or load shortcircuit and automatically returns the output to normal
when the cause is eliminated.
The overcurrent protection circuit shows a drooping characteristic. Ensure that the load to be used is at least with
the minimum resistance specified for each series.

■ Recommended pattern
[mm]
(1) The CHVM series uses a metal case. When mounting onto a doublesided board, wiring to this converter
should be on a soldered surface. When wiring, pay enough attention to creepage distance because of the high
voltage of this converter.
(2) When mounting onto a doublesided board, make the round on the parts surface of the high voltage output
terminal as small as possible.
(3) Connect the case of the CHVM series to Vin or Com. Try to reduce impedance to the ground as much as
possible.

■ Setting and adjustment of output voltage
The output voltage of the CHVM series can be set and adjusted by external voltage and external variable resistor.
●In the above characteristic graph (output voltage  VR resistance characteristic), the resistance R1 and R2 are for
a guideline. When setting output at a fixed voltage with a fixed resistor, do so after determining R1 and R2 using
a variable resistor.
●Do not apply 6V+3% or more voltage to Vcont.
●Use a variable resistor with a good temperature coefficient.
●It is preset that when the resistance of the variable resistor is 5.0KΩ, 6.0V is applied to the Vcont terminal to
obtain 100% output voltage. Since the tolerance of the resistance value largely affects the maximum output
voltage, set the resistance value at 5.0KΩ±5%.

■ Description of Vref terminal (reference voltage output)
This terminal is used for controlling output voltage with a variable resistor. Vref outputs a reference voltage of
6V. A 5KΩ external resistor is used in this case.
Since resistance value (tolerance) of an external resistor affects the Vref terminal voltage preset value and
determines output voltage, ensure that the resistor has high accuracy of 5KΩ±5%. The type of the variable resistor
(5KΩ) does not matter, but those of a good temperature coefficient are recommended.
■ Temperature derating
■ Protection against reverse connection
Reverse connection of input voltage may result in the breakage of a converter. If there is any possibility for a
reverse connection, add a diode and a fuse to the input circuit as shown below.
■ Recommended soldering conditions
Observe the following conditions for soldering each part.
(1) Soldering iron 340  360°C 5 seconds
(2) Dip solder bath 230  260°C 10 seconds

■ To reduce output noise further
The CHVM series basically does not require any additional parts, but to reduce output noise further, add Capacitor
C2 as shown below.
To reduce output noise even further, position C2 near the Load with the shortest inputoutput wiring while paying
attention to creepage and spatial distances.
Point!
(1) Add a capacitor of a good high frequency characteristic to the input side.
(2) Design a pattern for the ground (common) line to be thick and short so as to reduce common impedance.
(3) Ensure that a capacitor to add to the output side shall have a sufficient withstand voltage and shall be attached
to the terminal end. Try to make the lead wires of the capacitor the shortest possible in this case as well. In
addition, with a load requiring a certain response speed, pay attention to the time constant of the capacitor.
■ Safety standard
The CHVM series has attained the UL609501, CSA609501 certification.
When using the CHVM series as a Recognized certified product please mount an input fuse as shown below.
Choose a fuse(F1) from below:
