HIGH POWER PLATING RECTIFIER
USER MANUAL
VOLTEQ

Please read the user manual carefully before operating this rectifier.
Warning: Do not connect any load to the rectifier before it's turned on. Likewise, make sure to
disconnect the load before shutting down the rectifier. Damages to the rectifier may occur if you do not
follow this. Such damages are not under warranty.
Warning: If you are running inductive load like magnetic coils, DC motors, stepper motors, etc.,
make sure to change the voltage/current slowly, and NEVER turn the rectifier on or off with a inductive
load connected!
Warning: Do not attempt to inspect or repair the rectifier unless it has been powered off for at least
one minute.
Warning: The copper wires/terminals maybe be hot after the rectifier has been turned on.
Warning: Vapors from plating tank can be corrosive to the electronic components, damages caused
by corrosion is not under warranty.

I. Overview
HY series high power plating rectifiers are specialized rectifiers made for plating industry. The
rectifiers have high efficiency, high output, and are designed for continuous operation. The rectifiers
have built-in over current, over voltage, and over temperature protection. They can act as constant
voltage as well as constant current DC rectifier. These rectifiers are great choice for anodizing, plating,
electrolysis, hydrogen generation, and other applications that require high output power. The table
below list the current models available from Volteq.

III. The operation procedures
1. Check to ensure the AC plug is secure and wired correctly for the polarity. Check to ensure the output
is connected correctly and securely.
2. Check to ensure power switch and output switch are in "OFF" state, and the output adjustment knob

at the minimum position.
3. Plug into AC outlet, and then turn on the power switch (1). Check to make sure the fan is working.
4. Turn on the output (3). Select switch (4) to either "CV" or "CC" as your operating mode. If "CV" is
selected, the output voltage will be stable while the output current will change with the load; likewise, if
"CC" is selected, the output current will be stable while the voltage will change with the load.
5. Adjust knob (2) to set the output to the desired level.
IV. Maintenance
Routine inspection and maintenance is required for prolonged working life of the rectifiers:
1. Clean dust off the inside of the rectifier and cooling fan.
2. Clean off the oxide layer that may occur on the output copper wires and connectors.
3. Check to ensure that cooling fan is in good working condition all the time, replace the fan if it fails.
4. Regularly check and ensure that switch and circuit breaker are in good working condition and all
connectors are secure and firm.
5. The rectifier should not sit idle for more than a year, as the capacitor may change its characteristics if
not charged for a long time.

V. Troubleshooting
Symptoms
Possible Cause
Indicator light flashes, no voltage output
there maybe a short between output
terminals
fan may not be working properly or the
rectifier may have over-heated
over-current protection maybe trigged
Voltage output is normal, but no current output
connection to the positive and negative
terminals maybe loose
Circuit breaker jumps during operation
some components may have failed
internally
Output voltage or current is not stable
voltage or current meter may have gone
bad
Case is not grounded and is electrically hot
the environment maybe too humid
some internal components may have failed
