LISUN HFP-800 High Frequency Power Supply – After Sales Questions and Answers

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 HFP-800 sets parameters, the window display content is not related to the content marked on the front panel of the device
A1: The four windows on the front panel of the device are as follows:

During the test, the contents displayed in the window are consistent with those marked on the front panel. During the test, the window display definition (from left to right): output voltage, lamp voltage, lamp current, lamp power/output frequency.
The HFP-800 hardware has been improved, and the test parameter settings are slightly different. The old device is set as follows:
When setting parameters, the window display content is not related to the content marked on the front panel. When setting parameters, the window display definition (from left to right): no meaning, lamp open circuit voltage or starting voltage, no meaning, lamp rated voltage or working voltage.
The new device settings are displayed as follows:
