PULS SP960.241-S PLANET DIN Rail Power Supply, 24VDC 40A 960W, 1-Phase 100-240VAC Input, Screw Terminals

The PULS SP960.241-S is a 24 VDC, 40 A, 960 W single-phase DIN rail power supply from the PULS PLANET SP series, the top-of-the-line industrial range from PULS. In a housing only 96 mm wide, it delivers 95.1% efficiency at 120 VAC (96.4% at 230 VAC), 1152 W of continuous BonusPower up to +45°C, and 1440 W peaks for up to 5 seconds at temperatures up to +70°C. That headroom lets you size for the steady-state load instead of the inrush spikes from motors, drives, solenoids, and heavily capacitive loads.

Key Features

• Dynamic BonusPower Management: continuously tracks output power and delivers 110% of rated power for 30 s or up to 150% for 5 s, with 120% available continuously up to +45°C
• Compact 96 mm width: 960 W of 24 V power with a small DIN rail footprint for crowded control panels
• High efficiency, low idle loss: only 2.6 W power loss at no load and 49.5 W at full load on 120 VAC, reducing panel heat and operating cost
• Fuse breaking current: typically 80 A for up to 12 ms to reliably trip fuses and breakers on faulted output branches while the output stays above 20 V
• Hiccup^PLUS overload protection: protects both the supply and downstream equipment, with automatic restart once the overload clears
• Back-feed resistant: tolerates up to 35 V / 2 J fed back from regenerating motors or other loads, whether the unit is on or off
• DC OK relay contact and LED: remote diagnostics through an isolated relay contact plus a green/red front-panel status LED
• Parallel Use link: front-panel jumper switches the unit into load-sharing mode for paralleled or redundant systems
• Hazardous location rated: Class I Division 2 Groups A, B, C, D, ATEX and IECEx Zone 2 (T4)
• 3-year PULS warranty

How Dynamic BonusPower Works

Instead of a fixed peak rating, the SP960.241-S monitors output through a power-time integral. The less extra power a load draws, the longer BonusPower stays available. After a peak, the supply recovers in seconds, so repeated motor starts and actuator cycles are supported without nuisance shutdowns.

Typical Applications

• Machine control panels with servo drives, VFDs, brakes, and solenoid banks that create short high-current demands
• Packaging, material handling, and conveyor systems with frequent motor starts
• Semiconductor process equipment requiring SEMI F47 voltage sag immunity
• Oil and gas, chemical, and other Class I Div 2 / Zone 2 hazardous locations
• Redundant and paralleled 24 V systems, and 24 V lead-acid battery charging (two 12 V SLA/VRLA batteries in series)

Approvals and Compliance

cULus Listed to UL 61010-2-201 (E-File E198865, US and Canada), CB Scheme to IEC 61010-2-201 and IEC 62368-1, ATEX (EPS 25 ATEX 1 144 U, II 3G Ex ec nC IIC Gc), IECEx (IECEx EPS 25.0040U), Class I Division 2 Groups A, B, C, D, SELV/PELV, SEMI F47, CE, REACH, WEEE, and China RoHS 2. EMC emissions meet Class B per EN 55011 and EN 55032, and the unit complies with FCC Part 15.

Installation Notes

• Mount on a 35 mm DIN rail (EN 60715) with input terminals on the bottom. Other orientations require output derating; hazardous location use requires the standard vertical orientation.
• Keep 40 mm clearance above and below and 5 mm on each side (15 mm next to a heat source or another power supply in parallel or series).
• Approved for branch circuits up to 30 A (UL) without additional protection. If an external breaker is used, choose 16 A minimum, B or C characteristic.
• Protective earth connection is required (Class I equipment). Do not operate with DC input.
