Schneider ABL8RPS24100 Power Supply Modicon 24V 10A

Schneider Electric ABL8RPS24100 Modicon Regulated Power Supply

Product Introduction

The ABL8RPS24100 belongs to Schneider Electric’s Modicon power supply range. This regulated switch-mode unit converts AC power to stable 24V DC for PLCs, relays, sensors, and other automation components. Its wide input voltage range accommodates various global mains standards. Additionally, the compact design saves space inside control cabinets. For engineers seeking a robust and efficient power source, the ABL8RPS24100 delivers consistent performance under demanding conditions. Its comprehensive protection features also safeguard downstream equipment.

Key Technical Specifications

This power supply accepts a nominal input of 100–120V AC single-phase or 200–500V AC phase-to-phase. Input voltage limits span from 85 to 132V AC and 170 to 550V AC, offering exceptional flexibility. Output is fixed at 24V DC with a current rating of 10A, providing 240W of continuous power. Inrush current reaches 30A during startup, which is normal for this design. Power factor measures 0.68 at 240V AC and 0.69 at 120V AC. Efficiency hits 87% at full load, reducing energy waste. Power dissipation is rated at 31W, contributing to manageable heat output.

Output Protection and Adjustment

The ABL8RPS24100 includes multiple built-in protective features. Overload protection uses manual or automatic reset, while overvoltage protection trips at 30–32V with manual recovery. Short-circuit protection also offers manual or automatic reset options. Undervoltage protection activates when output drops below 21.6V. Thermal protection shuts down the unit in case of excessive heat and resets automatically when temperatures normalize. Output voltage can be adjusted between 24 and 28.8V, giving you fine-tuning capability for specific load requirements.

Communication and Monitoring

This power supply includes diagnostic relay contacts for remote monitoring. Two status LEDs provide clear visual feedback: one green/red LED indicates output voltage status, while another green/red/orange LED shows output current conditions. These indicators help maintenance staff quickly identify faults without opening the cabinet. The diagnostic relay can interface with PLC inputs or alarm panels, enabling automated fault reporting. For system integrators, this feature simplifies predictive maintenance and reduces downtime.

Mechanical and Mounting Details

Dimensions are 145 mm deep, 125 mm high, and 86 mm wide. Net weight is approximately 1 kg (2.2 lbs), with gross weight at 1.45 kg including packaging. Mounting supports both 35 x 7.5 mm and 35 x 15 mm symmetrical DIN rails. The unit operates in a vertical position for optimal cooling. Connection terminals use removable screw blocks: input accepts 0.5–4 mm² (AWG 22–12), output accepts 0.5–4 mm², and ground connections use the same range. The diagnostic relay uses a 2 x 2.5 mm² terminal block. Dielectric strength ratings are 3500V between input and ground, 4000V between input and output, and 500V between output and ground.

Frequently Asked Questions (FAQ)

Q1: Can the ABL8RPS24100 be used with a 110V AC input only?
A1: Yes, the ABL8RPS24100 accepts 100–120V AC single-phase as its nominal input, so it works perfectly on 110V systems.

Q2: Is it possible to parallel two units for higher current?
A2: Yes, this model supports parallel output coupling. You can connect multiple units to share the load, though proper diode isolation is recommended.

Q3: What happens if the output is short-circuited?
A3: The short-circuit protection activates immediately. Depending on your setting, the unit will either auto-reset or require manual reset after the fault clears.

Q4: Does this power supply require a cooling fan?
A4: No, the ABL8RPS24100 uses natural convection cooling. Ensure adequate clearance around the unit for proper airflow.

Q5: Can I mount this unit horizontally instead of vertically?
A5: The recommended operating position is vertical. Horizontal mounting may reduce cooling efficiency and require derating.
