INSTALLATION WARNING
・ When installing, ensure that work is done in accordance with the instruction manual. When installation is improper,
there is risk of electric shock and fire.
・ Installation shall be done by Service personnel with necessary and appropriate technical training and experience.
There is a risk of electric shock and fire.
・ Do not cover the product with cloth or paper etc. Do not place anything flammable around. This might cause damage,
electric shock or fire.
WARNING ON USE
・ Do not touch this product or its internal components while circuit in operation, or shortly after shutdown. You may
receive a burn.
・ While this product is operating, keep your hands and face away from it as you may be injured by an unexpected situation.
・ There are cases where high voltage charge remains inside the product. Therefore, do not touch even if they are not in
operation as you might get injured due to high voltage and high temperature. You might also get electric shock or burn.
・ Do not make unauthorized changes to this product nor remove the cover as you might get an electric shock or might
damage the product. We will not be held responsible after the product has been modified, changed or dis­assembled.
・ Do not use this product under unusual condition such as emission of smoke or abnormal smell and sound etc. Please stop
using it immediately and shut off the product.
It might lead to fire and electric shock. In such cases, please contact us. Do not attempt repair by yourself, as it is
dangerous for the user.
・ Do not operate and store these products in environments where condensation occurs due to moisture and humidity.
It might lead fire and electric shock.
・ Do not drop or apply shock to this product. It might cause failure. Do not operate these products mechanical stress is
applied.
CAUTION ON MOUNTING
・ Confirm connections to input/output terminals are correct as indicated in the instruction manual before switching on.
・ Input voltage, Output current, Output power, ambient temperature and ambient humidity should be kept within
specifications, otherwise the product will be damaged.
・ Input line, please use the wires as short and thick as possible.
・ Do not use this product in special environment with strong electromagnetic field, corrosive gas or conductive substances
and direct sunlight, or places where product is exposed to water or rain.
・ Please shut down the input when connecting input and output of the product.
・ When installing in environment where conductive foreign, dust and liquid may be present,
please consider penetration of above foreign material in the power supply by installing filter, to prevent trouble or
malfunction.

    TDK­Lambda CHVM1R5 Series INSTRUCTION MANUAL CAUTION ON USE • Product individual notes are shown in the instruction manual. If there is any difference with common notes individual notes shall have priority. • Before using this product, be sure to read the catalog and instruction manual. There is risk of electric shock or damage to the product or fire due to improper use.

  • Page 4 TDK­Lambda CHVM1R5 Series INSTRUCTION MANUAL The CHVM series is medium­high voltage DC­DC converters featuring an ultracompact size. With a pentahedron metal shield case, ripple noise has been reduced to as low as 5mVp­p. Output voltage can be adjusted by external voltage or external variable resistor. The built­in short circuit and overcurrent protection provide high reliability and a long life.

Between ON/OFF terminal (5) and ­Vin terminal (2) (1) Output OFF when opened (2) Output ON when short­circuited (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.
