( J ) POOR LOAD REGULATION.
POOR LOAD REGULATION
Load Terminal Nut inside Unit
might be Loose.
Is there any Oscillation Reduce Resistor R6 ( 2.2K ) on
in CV Mode ? F/Panel PCB until Oscillation dies
OUT. If Oscillation still Prevail
reduce R9 to 2K on F/Panel PCB.
Is Capacitor C4 and C2 Leaky ?
Replace It.
1. Load Terminal might be Loose. Ensure Terminals are tightened properly with
Terminal Nuts inside the Unit.
2. There might be Oscillation at Output in CV Mode. Adjust Resistor R6 & R9
until Oscillations die out.
3. Check Capcitor C4 and C2 on PREG PCB. It might be Leaky.
( K ) CV, CC, LED NOT GLOW.
1. Check the LED's. it might be Leaky, Open or Short.
