Technical Specifications
Core Function & Design
The
HIMA F7126 is a dedicated power supply module engineered for PES H51q automation systems. Specifically, it functions as a DC/DC converter that converts a 24V DC main supply into a stable 5V DC output to power system components. Additionally, it features safe isolation between the input and output voltages, ensuring electrical safety and preventing interference between circuits.
Furthermore, the F7126 is equipped with essential protection features to ensure reliable operation. It includes overvoltage protection, current limitation, and a short circuit proof output, which safeguards both the module itself and the connected automation system components from damage.
Front Plate Features
The front plate of the
HIMA F7126 is designed for ease of use and maintenance. It includes a test socket that allows users to quickly check the module’s output voltage without disconnecting any wiring. Additionally, a potentiometer is provided for stepless adjustment of the output voltage, enabling users to fine-tune the voltage to meet specific system requirements.
This user-friendly design simplifies installation, testing, and maintenance, reducing downtime and ensuring the module operates at optimal performance levels.
Redundant Use Guidelines
When using the HIMA F7126 power supply modules in redundant configurations, careful attention to output voltage balance is required. Specifically, the difference between the output voltages of the redundant modules may not exceed 0.025 V. This requirement prevents unbalanced loading, which could lead to premature module failure or inconsistent system performance.
Following this guideline ensures the redundant setup operates reliably, providing continuous power supply even if one module fails.
Input & Primary Fuse Specifications
The HIMA F7126 operates with a 24 V DC input voltage, which can vary by -15% to +20% without affecting performance. The input ripple (rpp) must be less than 15% to ensure stable operation of the DC/DC conversion process.
Additionally, the module requires a primary fuse of 6.3 A träge (slow-blow), which protects the module from excessive input current and prevents damage during power surges or faults.
Output Voltage & Current Parameters
The F7126 provides a 5 V DC output voltage that is adjustable steplessly within a range of ± 0.5V. The factory adjustment is set to 5.4 V DC ± 0.025 V, ensuring consistent performance right out of the box.
It delivers a maximum output current of 10 A, with a current limitation set to approximately 13 A. This current capacity is sufficient to power multiple components in the PES H51q system, while the current limitation prevents overloads.
Protection & Efficiency
The HIMA F7126 is equipped with overvoltage protection set to 6.5 V ± 0.5V, which triggers if the output voltage exceeds this threshold to protect connected devices. It also boasts an efficiency rate of ≥ 77%, ensuring minimal energy loss during the DC/DC conversion process.
Moreover, the module complies with Interference Limit class B according to VDE 0871/0877, meaning it emits minimal electromagnetic interference and can operate reliably in environments with other electronic equipment.
Mechanical & Environmental Parameters
Mechanical Dimensions & Construction
The HIMA F7126 has a space requirement of 8 TE (Terminal Equipment), a standard size for industrial power supply modules. This design ensures it fits seamlessly into PES H51q system racks, allowing for easy integration into existing control cabinets.
The module features a robust construction built to withstand harsh industrial environments, ensuring long-term reliability and consistent performance even in challenging conditions.
Environmental Requirements
The F7126 operates reliably in typical industrial environments, withstanding a wide range of operating temperatures and humidity levels. Its compliance with Interference Limit class B (VDE 0871/0877) ensures it can operate alongside other electronic devices without causing or being affected by electromagnetic interference.
Additionally, its durable design resists vibration and mechanical stress, making it suitable for use in various industrial settings such as chemical plants, power stations, and manufacturing facilities.
Installation Guide
Pre-Installation Preparation
Before installing the HIMA F7126, check the PES H51q rack slot to ensure it matches the module’s 8 TE space requirement. First, turn off the system power completely to avoid electrical damage during installation. Next, prepare the necessary tools, including a screwdriver, wire strippers, and the 6.3 A slow-blow primary fuse.
Additionally, confirm that the input power supply is 24 V DC and that the input ripple (rpp) is less than 15%. If using the module in a redundant configuration, prepare multiple F7126 modules and ensure their output voltages can be adjusted to within 0.025 V of each other.
Step-by-Step Installation
Installing the HIMA F7126 aligns with standard industrial power supply module installation procedures. First, align the module with the appropriate 8 TE slot in the PES H51q rack and slide it in until it clicks into place securely. Next, secure the module to the rack using the provided screws to ensure stability and prevent loose connections during operation.
After physical installation, install the 6.3 A slow-blow primary fuse in the designated slot. Then, connect the 24 V DC input wiring to the module’s input terminals, ensuring correct polarity to avoid damage. Connect the 5 V DC output wiring to the system components that require power, again verifying correct polarity.
Finally, if using the module in a redundant setup, adjust the potentiometer on each F7126 to ensure the output voltage difference between modules is no more than 0.025 V. Power on the system and use the front plate test socket to verify the output voltage is within the desired range.
Post-Installation Check
Once the F7126 is installed and powered on, test its functionality to ensure normal operation. Check the output voltage using the test socket to confirm it matches the factory setting (5.4 V DC ± 0.025 V) or the adjusted value. Verify that the overvoltage protection and current limitation features are working correctly by simulating minor overloads (if safe to do so).
For redundant setups, confirm the output voltage balance between modules is within the 0.025 V limit. If any issues arise, recheck the wiring, fuse, and voltage adjustments to resolve them promptly.
