4. Block Diagram

The block diagram illustrates the internal functional architecture of the HRP-600-24 power supply, highlighting key components and their interconnections.

Figure 2: Internal block diagram of the HRP-600-24 power supply. The diagram shows the input (I/P) and frame ground (FG) connections leading to an EMI filter. This is followed by an active inrush current limiting circuit, rectifiers & PFC, and a power switching stage. The output then goes through another set of rectifiers & filter. Control circuits include PFC control and PWM control, with protection features like O.T.P. (Over Temperature Protection), O.L.P. (Over Load Protection), and O.V.P. (Over Voltage Protection) integrated into the detection circuit. A DC OK signal is also provided.

• EMI Filter: Reduces electromagnetic interference.
• Active Inrush Current Limiting: Prevents high current surges during power-on.
• Rectifiers & PFC: Converts AC to DC and performs Power Factor Correction.
• Power Switching: High-frequency switching for efficient power conversion.
• PFC Control & PWM Control: Regulates power factor and output voltage/current.
• Detection Circuit: Monitors for Over Temperature (O.T.P.), Over Load (O.L.P.), and Over Voltage (O.V.P.) conditions.
• DC OK Signal: Provides an indication of stable DC output.

5. Performance Curves

These curves illustrate the operational characteristics and limitations of the power supply under various environmental and input conditions.

5.1 Derating Curve

Figure 3: Derating Curve. This graph shows the maximum permissible load percentage as a function of ambient temperature. The power supply can operate at 100% load up to approximately 50°C. Beyond this temperature, the load capacity linearly decreases, reaching about 50% load at 70°C. Operation above 70°C is not recommended.

5.2 Output Derating VS Input Voltage

Figure 4: Output Derating VS Input Voltage. This curve indicates the maximum load percentage the power supply can deliver based on the input voltage (at 60Hz). The unit can deliver 100% load when the input voltage is above approximately 100V. Below this, the load capacity decreases, reaching about 80% load at 85V input. Ensure the input voltage is within the specified range for optimal performance.

6. Setup

Follow these steps for safe and correct installation of the HRP-600-24 power supply.

1. Mounting: Securely mount the power supply using the designated M4 screw holes. Ensure the mounting surface is stable and can support the unit's weight.
2. Ventilation: Position the unit to allow for proper airflow as indicated in the mechanical drawing (Figure 1). Do not obstruct the fan or ventilation openings. Maintain adequate clearance around the unit for heat dissipation.
3. Wiring: Connect the AC input wires (Live, Neutral, Ground) to the corresponding terminals as per Section 3.1. Ensure all connections are tight and secure to prevent loose contacts and potential hazards.
4. DC Output Connection: Connect the DC load to the +V and -V output terminals as per Section 3.2. Observe correct polarity.
5. Remote Sense/Control (Optional): If using remote sense or remote ON/OFF control, connect the CN100 connector as per Section 3.3. Remote sense helps compensate for voltage drop across the load wires.
6. Grounding: Ensure the frame ground (FG) terminal is properly connected to earth ground for safety.

7. Operating Instructions

Once installed, the HRP-600-24 power supply is designed for straightforward operation.

• Power On: Apply AC input voltage within the specified range (Universal AC input / Full range). The unit will power on and provide DC output.
• Output Voltage Adjustment: If equipped, use the SVR1 (Vo ADJ.) potentiometer to fine-tune the output voltage within its adjustable range. Refer to the mechanical drawing for its location.
• Monitoring: The DC OK signal (if connected) indicates stable output. Monitor the load to ensure it remains within the power supply's capacity, especially considering ambient temperature and input voltage derating curves.
• Protection Features: The unit includes built-in protections against short circuit, overload, over voltage, and over temperature. In case of a fault, the power supply may shut down to protect itself and the connected load. Address the fault condition before restarting.

8. Maintenance

The HRP-600-24 power supply is designed for long-term reliability with minimal maintenance. However, periodic checks can help ensure optimal performance.

• Cleaning: Periodically inspect the ventilation openings and fan for dust accumulation. Clean with compressed air or a soft brush to maintain proper airflow. Ensure power is disconnected before cleaning.
• Connections: Routinely check all input and output wiring connections for tightness and signs of corrosion. Re-tighten if necessary.
• Environment: Ensure the operating environment remains within the specified temperature and humidity ranges. Avoid exposure to excessive dust, moisture, or corrosive substances.
• Fan Operation: Listen for unusual noises from the cooling fan, which could indicate a potential issue.

9. Troubleshooting

If the power supply is not functioning as expected, refer to the following common issues and their potential solutions.

• No Output Voltage:
  • Check AC input power: Ensure the power cord is securely connected and the AC source is active.
  • Check input fuse/breaker: Verify that the circuit breaker or fuse supplying power to the unit has not tripped.
  • Verify wiring: Confirm all input and output connections are correct and secure.
  • Overload/Short Circuit: Disconnect the load and check if the output voltage returns. If so, the load may be drawing too much current or have a short circuit.
  • Over Temperature: Allow the unit to cool down. Ensure proper ventilation.
• Output Voltage is Unstable or Incorrect:
  • Check load: Ensure the load is not fluctuating excessively or drawing intermittent high currents.
  • Remote Sense: If remote sense is used, verify connections. If not used, ensure +S and -S terminals are properly connected to +V and -V respectively at the power supply output.
  • Input Voltage: Confirm the AC input voltage is stable and within the specified operating range.
• Unit Shuts Down Periodically:
  • Overload: The load may be exceeding the power supply's capacity. Reduce the load.
  • Over Temperature: Check for blocked ventilation or high ambient temperatures. Refer to the derating curve.
  • Intermittent Short Circuit: Inspect the load and wiring for intermittent short circuits.

If these steps do not resolve the issue, contact technical support.
