LISUN HFP-800 LPS-3 RB-3 High Frequency Fluorescent Lamp Test System – After-sales Frequently Asked Questions (FAQ)

The HFP-800 High Frequency Power Supply works with LPS-3 (Lamp Preheat Assistant Source) and RB-3 (Adjustable Resistance Ballast) to be an IEC Standard Test System which used to test the high frequency fluorescent Lamp such as T5 Tube. Please visit this page to view How to Measure the High Frequency Fluorescent Lamp. It is fully meet the ANSI-ANSLG-C78.81, ANSI-ANSLG-C82.11, IEC62776 , GB/T-15144 Standard.

Features:
• Program control output voltage and easy operation
• Set data easily with a memory chip, unnecessary to set for many times
• Display on four windows, each window shows one parameter independently
• Application for all kinds fluorescent lamps such as 50Hz/60Hz T8/T12 tube or 25KHz T5 Tube
• It is according to double-ended fluorescent lamps adoptting the IEC 60081 (GB/T10682) and the single-ended fluorescent lamps adoptting the IEC 60901 (GB/T17262)

Specifications:
• Range for output voltage: 10~600V (Adjustable)
• Range for output current: 0~0.600A
• Range for output frequency: 25KHz
• Range for output capacity: 0~300W (Special request to 500W)
• Range for Voltage stability: 0.5%/30 minutes
• Range for frequency stability: 0.02%

Q1: When setting parameters for HFP-800, the window display content is not related to the content marked on the front panel of the instrument.
A1: The four windows on the front panel of the device are as follows:

HFP-800 high frequency power supply front panel

During the test, the window display content is consistent with the content marked on the front panel. The window display definition during the test (from left to right): output voltage, lamp voltage, lamp current, lamp power/output frequency.

The HFP hardware has been improved, and the test parameter settings are slightly different. The old version instrument is displayed as follows when setting: When setting parameters, the window display content is not related to the content marked on the front panel. The window display definition during setting (from left to right): no meaning, lamp open circuit voltage or starting voltage, no meaning, lamp rated voltage or working voltage.

The new version instrument is displayed as follows when setting:

Q2: There are output terminals on the front panel and also on the back panel of the RB-3. How to do the wire connection?
A2: The output terminals on the front and back panels have the same function, so you only need to use any set of them. Note: When using one set of them, the other set of terminals must not be connected to any wires, otherwise there may be unpredictable dangers.
