Features

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.

When the load factor is 0 - 30%, the switching power loss is

reduced by burst operation, which will cause ripple and ripple

noise to go beyond the specifications.
