50 % load change
Over Load Protection
(OLP) When the average power rating exceeds 125%-
150% of maximum power, output voltages reduced to
a safe dissipation level; protects against short circuit of
any output.
150% of maximum power, output voltages reduced to
a safe dissipation level; protects against short circuit of
any output.
Over Voltage Protection (OVP) 124 % ±8 % on output.
Over Circuit Protection Withstands a continous short without damage; returns
automatically to regulation upon removal of short.
No Load Operation
No damage to power supply when operating at no
load.
