The IS200HFPRG1A is a High-Frequency Power Supply Board (HFPR) designed and manufactured by General Electric (GE).
While similar in name to the HFPA boards (High-Frequency AC/Fan Power Supply) typically found in the main Mark VI control rack, the IS200HFPRG1A is often associated with power delivery in GE’s Drive Control systems, particularly the Innovation Series Medium Voltage (Type H) Drives.
⚡ Key Functions and Specifications
This board’s primary role is to provide stable, regulated, high-frequency power within the drive control system.
-
Function: It is a power converter that takes an AC input and regulates it for internal system use.
-
Input: It typically operates using a 24 VAC square wave input at 50/60 Hz. This input is usually supplied and regulated by a separate constant voltage control power transformer.
-
Power Delivery Mechanism: It utilizes a high-frequency transformer to efficiently convert and deliver power, which helps minimize energy losses and reduce the board’s size (high power density).
-
Connectivity: The board is equipped with:
-
Six Plug Connectors, including:
-
HFPL1 and HFPL2 for power supply connections.
-
FAPL1 and FAPL2 for connecting and powering cooling fans.
-
C1PL and C2PL for external capacitor connections.
-
-
-
Diagnostics and Protection:
-
It features two LEDs to serve as visual indicators for the power supply output status.
-
It incorporates five fuses to protect the components and circuitry from electrical faults.
-
In summary, the IS200HFPRG1A is a specialized power supply PCB that is essential for the operation and cooling of the electronics within GE’s Medium Voltage Drive systems.
