Question: When the adjustable dc regulated power supply will work in constant current and constant voltage
Answer:
1. Constant current---When CC indicator ON mean the power supply working under constant current and the current must be the max output and can be adjust but voltage can not adjustable
2. Constant Voltage ---the voltage with max output and can be adjust but the current can not adjust

Question : Does the Adjustable dc regulated power supply support wide range input ?
Answer:
1. No. our adjustable dc regulated power supply design did not support wide range input
2. It is support input voltage as below
Single phase 110VAC+/-15%,Single phase 110VAC+/-20%,
Single phase 220VAC+/-15%,Single phase 220VAC+/-20%,
3 phase 380VAC+/-15%,3 phase 380VAC+/-20%
3 phase 415VAC+/-15%,3 phase 415VAC+/-20%
3 phase 450VAC+/-15%,3 phase 450VAC+/-20%
