Operation notes

(1) The output current needs to be reduced as the ambient temperature rises.(Please refer to the derating

curve.)

(2) Lead pins should be securely connected. If lead pins are not securely connected, irregular voltages could

be produced, causing breakdowns and damage.

(3) Please I/O external capacitors as near as possible to the connection pins. Output ripple voltage might be

larger.

(4) Be minded to use external parts within the specified range. In case that the parts with other than the

specified range, it will not only result in dissatisfactory fulfillment of the specifications but may also cause

the failures.

(5) Watch out for chattering when the power is turned on. If chattering when the power is turned on, do not

use exceeding the maximum input voltage.

(6) In the case of loads such as motors or relays, take measures so that over voltage is not applied to the

module input / output terminals due to counter-electromotive force when turning power on / off, and

current does not exceed absolute maximum rating.

(7) Make sure that the absolute maximum rated value is not exceeded when locking, reversely rotating, or

starting the motor.

(8) Condensation

When the insulation between the terminals is deteriorated due to condensation, normal activation may

sometime be hindered. Please be careful with the condensation especially between the external coils,

and between the input terminals.

(9) Operating temperature

Be sure to use within the derating curve. Particularly, in case that this product is used in the closed vessel,

be sure to measure the temperature, and make sure that it is within the derating curve.

(10) Do not attempt to apply static electricity at the time of installation or storage. It may cause breakage.

(11) The over output voltage should not be applied to the output terminal.

(12) Since there may be a case that the output voltage cannot be increased if the reverse voltage is applied

to the output terminal, make sure that the reverse voltage should not be applied when supplying the

power source.

(13) In case that vibration is significant, be minded to use this product after fixing it.
