- Compact design (Depth: 99mm 3.90inches)

- UL508 approved (Except option -J), and complies with SEMI F47

- Various connection interface options (vertical terminal [-T], AMP connector [-J])

*1 This is the result of measurement of the testing board with capacitors of 22mF and 0.1mF placed at 150

mm from the output terminals by a 20 MHz oscilloscope or a ripple-noise meter equivalent to Keisoku-

Giken RM103.

See 1.6 of Instruction Manual for more details.

*2 Drift is the change in DC output for an eight hour period after a half-hour warm-up at 25C.

*3 As for DC input, consult us for advice.

*4 Consult us about dynamic load and input response.

*5 Output power derating is required. See 3.2 in Instruction Manual.

*6 See 3.3 in Instruction Manual for more details.

*7 Consult us about safety agency approvals for the models with optional functions.

*8 Consult us about other classes.

*

Do not use the power supply in overcurrent conditions or in unspecified input voltage ranges.

Otherwise the internal components may be damaged.

*

Parallel operation is not possible with this mode.

*

Sound noise may be heard from the power supply when used for pulse load.
