Product introduction

The GE IS420UCSBH1A is a high – reliability uninterruptible control system power supply designed to safeguard critical industrial control systems from power disruptions. In industrial settings where continuous operation is essential, such as power generation plants, oil refineries, and manufacturing facilities, even a brief power outage can lead to significant production losses, equipment damage, or safety hazards. The IS420UCSBH1A steps in to bridge these power gaps.

It acts as a reliable power source, providing a stable 24 VDC output to connected control devices. When the primary AC power is available, the unit not only powers the connected systems but also charges its internal sealed lead – acid battery. In the event of an AC power failure, the battery immediately takes over, ensuring that the control system continues to operate without interruption. This seamless transition is crucial for maintaining the integrity of ongoing processes, allowing for an orderly shutdown or continued operation of essential control functions until power is restored.

Core advantages and technical highlights

Reliable backup power: The use of a sealed lead – acid battery, with a capacity optimized for industrial applications, ensures a consistent and reliable power backup. The battery can supply up to 10 A of current at 24 VDC for a typical backup time ranging from 10 to 30 minutes, depending on the load. This provides sufficient time for operators to either initiate a proper shutdown sequence or for the primary power source to be restored.

High – efficiency power conversion: With an efficiency of up to 90%, the IS420UCSBH1A minimizes power wastage. This not only reduces energy costs but also helps in keeping the unit cool during operation, enhancing its overall reliability. The high power factor of >0.95 ensures that the power supply draws minimal reactive power from the grid, reducing stress on the electrical infrastructure.

Remote monitoring and control: Equipped with an RS – 485 communication interface supporting the Modbus RTU protocol, the power supply can be integrated into a plant – wide monitoring and control system. Operators can remotely monitor the power status, battery charge level, and output voltage. In case of any faults or abnormal conditions, such as low battery voltage or over – current, the system can be configured to send alerts, enabling proactive maintenance and minimizing downtime.

User – friendly LED indicators: The front – panel LED indicators provide a quick visual status check of the power supply. The power status LED shows whether the primary AC power is present and the unit is operating correctly. The battery status LED indicates the charge level of the battery, while the output status LED shows if the 24 VDC output is stable. In case of a fault, the fault indication LED lights up, making it easy for on – site technicians to identify and troubleshoot issues.

Flexible mounting options: The 1U rack – mountable design makes it easy to integrate the power supply into standard 19 – inch equipment racks, commonly used in industrial control rooms. Additionally, with an optional wall – mounting kit, it can be installed in areas where rack space is limited, providing flexibility in installation based on the physical layout of the industrial facility.

Typical application scenarios

Power generation plants: In power plants, the IS420UCSBH1A is used to power critical control systems such as turbine control systems, generator protection systems, and power management systems. During a grid – side power outage, it ensures that these control systems remain operational, allowing for safe and controlled shutdown procedures. For example, it can keep the turbine governor control system running, preventing sudden over – speeds that could lead to catastrophic turbine damage.

Oil and gas refineries: In oil and gas refineries, continuous operation of control systems is vital to maintain safe and efficient production processes. The IS420UCSBH1A powers control valves, monitoring sensors, and distributed control systems (DCS). In the event of a power interruption, it enables the refinery to continue essential operations like maintaining pressure in pipelines, controlling the flow of hydrocarbons, and ensuring proper ventilation in hazardous areas, preventing potential safety incidents.

Manufacturing facilities: In manufacturing plants, especially those with automated production lines, power outages can cause significant disruptions. The IS420UCSBH1A is used to power programmable logic controllers (PLCs), robotic control systems, and quality control equipment. This ensures that ongoing production processes can be either gracefully halted or continue for a short period, reducing the risk of damaged products and costly production line restarts. For instance, in an automotive assembly plant, it can keep the robotic arm control systems running, preventing misaligned parts and production bottlenecks.

It also offers enhanced battery management features, providing longer battery life and more accurate state – of – charge monitoring.

GE IS420UCSBL1A: A lower – cost alternative with a smaller footprint. It has a lower output current (e.g., 5 A) and a slightly shorter backup time, but is ideal for less power – intensive control systems or applications where space is at a premium.

GE IS420UCSBM1A: This model comes with additional communication capabilities, such as Ethernet connectivity in addition to the RS – 485 interface. It allows for more seamless integration into modern, IP – based industrial networks and enables remote access and control from a wider range of devices.

Installation, commissioning and maintenance instructions

Installation preparation: Before installation, ensure that the location where the power supply will be installed meets the specified environmental conditions, such as temperature and humidity. Verify that the AC power source voltage is within the acceptable range of 85 – 264 VAC. If rack – mounting, ensure that the 19 – inch rack is properly grounded. For wall – mounting, use the appropriate wall – mounting kit and ensure that the wall can support the weight of the unit. When handling the unit, avoid dropping or subjecting it to excessive vibration, as this could damage the internal components, especially the battery.

Commissioning steps: After installation, connect the AC power input cable and the DC output cables to the appropriate devices. Power on the unit and check the LED indicators. The power status LED should light up green, indicating that the primary AC power is being received and the unit is operating correctly. The battery status LED should show the initial charge level of the battery. Use a multimeter to verify that the DC output voltage is 24 VDC. If the unit is to be integrated into a monitoring system, configure the RS – 485 communication settings, such as the baud rate, parity, and device address, according to the requirements of the monitoring software.

Maintenance suggestions: Regularly perform visual inspections of the unit. Check for any signs of physical damage, such as cracks in the casing or loose cables. Monitor the battery status using the LED indicator or the remote monitoring system. If the battery status LED indicates a low charge or if the backup time seems to be significantly reduced, it may be time to replace the battery. The battery should be replaced every 3 – 5 years under normal operating conditions. Update the firmware of the power supply (if available) periodically to ensure that it has the latest features and bug fixes. In case of any faults, refer to the user manual for troubleshooting steps. If the fault cannot be resolved, contact GE’s technical support.
