*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.
*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.
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.
*
*
Parallel operation is not possible with this mode.
Sound noise may be heard from the power supply when used for pulse load.
*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.
