DANGER 

Do not operate if the covers are damaged or removed in any way. 

-

 

The rectifier contains voltages that may be lethal even after the input 

supply has been removed

 

-

 

The rectifier contains components at High Temperatures that may burn if 

touched

Troubleshooting

Basic operation checks:

• Check power to the rectifier – check that the AC LED is on

• Check and resolve any fault conditions indicated by the status indicators

• Check that the display is showing that it is delivering current

• Disconnect load and battery leads. Connect a load to the battery terminals. Check the voltage across the load is 

   as expected

• Connect a current meter in series with the load. Adjust the load and check the current delivered by the rectifier 

   is as expected

Load Checks:

• Connect battery but disconnect the main load to rectifier. Connect a current meter in series with the battery. 

   Verify the current drawn by the battery from the SPS is as expected. Check that the battery takes the charge.

• Connect the DC load to the SPS with AC off and disconnect the battery. Turn AC on and check that the

   current drawn by the load is as expected, and within the capabilities of the SPS and battery.

Fine Adjustment Checks: 

(see 

Section 4

 on adjustments for instructions)

• Check Boost and Float voltages

• Check Boost to Float current

• Check Temperature Compensation Slope

• Check LVD operation

Fuses

Although there are fuses inside the rectifier, these are rated such that their failure indicates a fault requiring 

qualified service. Do not attempt to replace these fuses.

However for IEC 60950 the fuse ratings are required to be specified. The following fuses are soldered to the PCB:

• FH101 – 125mA 250V ETF Bussmann

FH1, FH2

FH200, FH401

Adjustments

The SPS is supplied from the factory with all the adjustments set for normal operation. These settings are detailed 

below. A competent technician only should adjust these settings.
