GE IS200BPPBH2CAA Power Supply Module

I. Product Overview

II. Core Functional Features

1. Multi-Specification DC Power Output

• +5V DC is mainly used to power the digital circuits of control modules, with a maximum output current of 10A;

• ±12V DC/±15V DC are suitable for analog circuits (such as the amplification circuits of signal acquisition modules), with a maximum output current of 5A;

• +24V DC is used to power digital input/output modules and sensors, with a maximum output current of 8A.

2. Dual Redundant Power Supply and Seamless Switching

3. Comprehensive Power Protection Mechanism

• Overcurrent Protection: When the output current of a certain channel exceeds 120% of the rated value, the protection circuit quickly cuts off the output of that channel to prevent damage to the module and subsequent equipment caused by load short circuits.

• Overvoltage/Undervoltage Protection: When the input voltage exceeds the range of 380V AC±15%/220V AC±15%, or the output voltage exceeds ±10% of the rated value, the module automatically stops output and triggers an alarm.

• Over-temperature Protection: When the internal temperature of the module exceeds 85℃, the over-temperature protection mechanism is activated to reduce the output power and trigger the high-speed operation of the cooling fan (if equipped). Normal output is resumed when the temperature drops below 60℃.

• Short-circuit Protection: When a short circuit occurs at the output terminal, the module instantly cuts off all outputs to avoid burning the power chips or circuits due to excessive short-circuit current.

4. Real-Time Status Monitoring and Fault Alarm

• Through built-in voltage sensors, current sensors, and temperature sensors, it collects key parameters in real time, such as input voltage, output voltage/current of each channel, and internal temperature of the module, and uploads the data to the system controller via the backplane bus.

• The module is equipped with 6 LED indicators (PWR: Power status, green; RUN: Operation status, green; FAULT: Fault status, red; +5V/+12V/+24V: Output status, green), which intuitively reflect the power supply status. For example, the extinction of an output indicator indicates abnormal power supply of that channel, and the flashing of the FAULT indicator indicates that the module is over-temperature or overcurrent protection is triggered.

III. Key Technical Parameters

1. Electrical Parameters

• Input Parameters: Supports dual-voltage input of 380V AC/220V AC, with an allowable voltage fluctuation range of ±15%; frequency range of 47Hz-63Hz, suitable for industrial power grid frequencies in most regions around the world; maximum input current of 15A (at 380V AC)/25A (at 220V AC); power factor ≥0.95, reducing harmonic pollution to the power grid.

• Conversion Efficiency: AC-DC conversion efficiency ≥90% (at full load), DC-DC conversion efficiency ≥92%, effectively reducing the module's own power consumption, minimizing energy waste, and meeting the needs of green industry.

• Anti-Interference Performance: Complies with the IEC 61000-6-2 industrial anti-interference standard, with ±2kV Electrostatic Discharge (ESD) protection, ±1kV Electrical Fast Transient (EFT) protection, and radio frequency radiation immunity ≥10V/m (80-1000MHz), enabling stable power supply in complex electromagnetic environments.

2. Environmental Parameters

• Operating Temperature: -20℃~70℃, supporting wide-temperature operation and adapting to scenarios such as high-temperature workshops and outdoor control cabinets;

• Storage Temperature: -40℃~85℃, with no risk of component aging or pin corrosion during long-term storage;

• Humidity: 5%~95% (non-condensing). The module surface is coated with a moisture-proof insulating layer, and key internal components adopt hermetic packaging, allowing use in high-humidity and high-salt-spray coastal environments;

• Vibration Protection: Complies with the IEC 60068-2-6 standard, capable of withstanding sinusoidal vibration with a frequency of 10-500Hz and an acceleration of 5g; complies with the IEC 60068-2-27 standard, capable of withstanding an impact of 50g acceleration (11ms pulse), avoiding interface loosening and component damage caused by equipment operation vibration or transportation impact.

3. Physical and Status Indication Parameters

• Dimensions: 6U VME board form factor (160mm×233mm×30mm), compatible with standard 19-inch industrial control cabinet installation, and supporting hot swapping (requires Mark VIe system authorization);

• LED Indicators: 6 status lights (PWR: Power input status, green; RUN: Normal operation status, green; FAULT: Fault status, red; +5V/+12V/+24V: Corresponding voltage output status, green). The RUN light stays on to indicate normal operation and blinks to indicate redundancy switching in progress; the FAULT light stays on to indicate a serious fault (such as short circuit, over-temperature) and blinks to indicate a minor fault (such as voltage deviation);

• Backplane Interface: 1 VME64x backplane interface, used for communication with the system controller to transmit power status data (such as output voltage/current, module temperature), support the upload of fault alarm signals, and receive power control commands from the controller (such as remote restart) at the same time.
