Functional Description
The IS200HFPR High Frequency Power Supply Board (HFPR) is used in Innovation
Series Medium Voltage - GP, Type H drives. It operates from a 24 V ac 50/60 Hz
square wave input supplied from a constant voltage control power transformer.
Isolated input connections are made at TB1-1 (AC1), TB1-2 (ACCOM), and TB1-3
(AC2) as shown in Figure 1. The HFPR board full-wave rectifies the input voltage
and outputs voltages as shown in Table 1. All input and output voltages are fuse
protected (see Table 1).
A bulk capacitor bank is provided on the board for power loss ride-through. The ride-
through time is load-dependent, and can be extended by adding two additional
external capacitors.
Two LEDs, PSOK1 and PSOK2, indicate that power supply outputs are normal.

Application Data
The HFPR board includes one terminal board, six plug connectors, five fuses, and
two LED indicators. There are no testpoints or adjustable hardware devices on the
board. Refer to Figure 2 for component locations. See Table 1 for fuses and the

LED Indicators
Two LED indicators monitor power supply outputs. PSOK1 (DS1) monitors the 48 V
ac output and PSOK2 (DS2) monitors the ±15 V dc output.
If PSOK1 LED is off, verify that fuse FU5 is not open.
If PSOK2 LED is off, verify that fuses FU3 and/or FU4 are not open.
If both LEDs are off, verify that the input power is present at TB1, and that fuses
FU1 and/or FU2 are not open.

Renewal/Warranty Replacement

How to Order a Board

When ordering a replacement board for a GE drive, you need to know:
How to accurately identify the part
If the part is under warranty
How to place the order

This information helps ensure that GE can process the order accurately and as soon
as possible.
Board Identification

A printed wiring board is identified by an alphanumeric part (catalog) number
located near its edge. Figure 3 explains the structure of the part number.

The boards functional acronym, shown in Figure 3, is normally based on the board
description
, or name. For example, the HFPR board is described as the High
Frequency Power Supply Board.
Warranty Terms

The GE Terms and Conditions brochure details product warranty information,
including warranty period and parts and service coverage. The brochure is
included with customer documentation. It may be obtained separately from the
nearest GE Sales Office or authorized GE Sales Representative.

Renewals
(spares or those not under warranty) should be ordered by contacting the
nearest GE Sales or Service Office.

Be sure to include the following when ordering any warranty or renewal parts:
Complete part number and description
Drive serial number
Drive Material List (ML) number

Note
All digits are important when ordering or replacing any board. The factory
may substitute later versions of boards based on availability and design
enhancements. However, GE Industrial Systems ensures backward compatibility of
replacement boards.

Handling Precautions


To prevent component damage caused by static
electricity, treat all boards with static sensitive handling
techniques. Wear a wrist grounding strap when
handling boards or components, but only after boards
or components have been removed from potentially
energized equipment and are at a normally grounded
workstation.

Printed wiring boards may contain static-sensitive components. Therefore, GE ships
all replacement boards in antistatic bags. 6 IS200HFPR High Frequency Power Supply Board
GEI-100312

Use the following guidelines when handling boards:
Store boards in antistatic bags or boxes.
Use a grounding strap when handling boards or board components (per previous
Caution criteria).
Replacement Procedures
To prevent electric shock, turn off power to the drive,
then test to verify that no power exists in the board
before touching it or any connected circuits.
To prevent equipment damage, do not remove, insert, or
adjust board connections while power is applied to the
equipment.
½
To replace the HFPR board
1.

Make sure that the drive in which the board resides has been de-energized.
(Refer to the appropriate Users Manual for complete de-energizing procedures,
GEH-6131 for air-cooled drives or GEH-6133 for liquid-cooled drives.)
2.

Open the drive control cabinet door, and using equipment designed for high
voltages, test any ele
