How to Operate

General Description

Use the following procedure to safely operate the power

supply.

The FAN4810 Evaluation Board is a power-factor-corrected

500W off-line power supply. The supply has a single 400V

output and operates over an input voltage range of 90 VAC to

265 VAC. The Evaluation Board uses an average mode boost

PFC that allows it to be fully complaint with IEC 61000-3-2

limits for harmonic emission.

1. Connect a 100W load across the output terminals

(J3 and J4).

2. Connect a DC voltmeter across the output terminals.

When operating the FAN4810 Evaluation Board there are

two things to keep in mind. A minimum load of 15 to 20

Watts is required to prevent output from rising to the OVP

point. This will provide continuous operation and prevent the

PFC from periodic shutdown due to OVP. Also, there is no

current inrush limiting included in the Evaluation Board.

Because of this it is suggested that the input voltage is

always ramped up slowly.

3. Connect an isolated variable AC source (such as a

variac) to input terminals J1 and J2. A DC source may

be substituted at the input for easier examination of the

waveforms.

4. Slowly increase the AC input voltage to at least 90VAC

(Do not exceed 265VAC). If applying a DC input

increase it to 120 Volts.

5. Conﬁrm that the output voltage increases as the input

voltage is increased.

Evaluation Kit Contents

The FAN4810 Evaluation Kit contains the following items:

6. As the input voltage approaches very close to 90VAC

(120VDC) the Board output should read approximately

404VDC within 5 sec.

1. FAN4810 Evaluation Kit Users Guide

2. Fully Functional FAN4810 Evaluation Board

7. Remove the AC input and verify that the output voltage

has dropped to zero.

Circuit Design

Refer to Application Note, AN-6004 for detailed design

information on this board.

8. Connect a 500W load across the output terminals and

reapply the AC input.

Performance Data

CAUTION!

To measure the Eval Board performance across the range

of permissible input voltages use an isolated Variac or

adjustable AC source. It is suggested that the input voltage is

increased slowly as the evaluation board has no inrush

current limiting.

The FAN4810 Evaluation Board contains voltage

potentials capable of causing serious injury, and compo-

nents that may shatter or explode if they fail. Appropri-

ate precautions must be taken to prevent injury should

such situations occur. The use of protective eyeware is

strongly recommended.

A typical FAN4810 evaluation board will have the perfor-

mance characteristics shown in Figure 1 when operated as

speciﬁed in the Test Conditions.

To safely observe circuit waveforms, an isolation

transformer should be used between the Evaluation

Board and the AC line.

Do not operate this board with DC/AC voltages

outside the design limits.

Replace circuit components only with those

recommended in the parts list of this User’s Guide.
