PRECAUTIONS * These units are not equipped with overvoltage or overcurrent protection circuit for input or output. (CE-0970 includes an overcurrent protection circuit) * Install external input/output capacitors as close to the unit's terminal as possible. Excessive noise voltage may result if they are placed too far apart. * These units are not equipped with input fuses. Please install an input fuse for safety if the input power capacity is 1A or greater or you require load protection in the unlikely event that the input and output are shorted due to a failure in the unit (0.5 to 1A withstand rush current fuse). * Parallel operation to increase output current is not possible. * These units cannot be washed.
* All specifications are subject to change without notice.
