■ Ratings/Characteristics

24/12-V Models (Basic Block: S8TS-06024

@/S8TS-03012@)

Note 1. Refer to page B-59 for details on adjusting the output voltage for parallel operation. If set to less than

−10%, the undervoltage detection

function may operate. Ensure that the output capacity and output current after adjustment do not exceed the rated output capacity and

rated output current respectively.

2. Class 2 approval does not apply to parallel operation.

3. The output current is specified at power output terminals.

4. Refer to the explanations of functions on page B-56 for details.

5. Be sure to mount End Plates (PFP-M) on both ends of the Power Supply.
