PULS
$607.50
The PULS TP480.241 is a 24 VDC, 20 A, 480 W three-phase DIN rail power supply from the PULS PLANET TP series. At only 49 mm wide, it runs directly on 380-500 VAC three-phase mains, reaches 96.5% efficiency at 3x 480 VAC, and provides 576 W of continuous BonusPower up to +45°C plus 960 W (200%) peaks for up to 5 seconds at temperatures up to +60°C. A front-panel LED bar shows output load at a glance, and the unit operates from -40°C to +70°C.
Key Features
- Dynamic BonusPower Management: delivers 130% of rated power for 22 s or up to 200% for 5 s at up to +60°C, with 120% available continuously up to +45°C
- Compact 49 mm width: a slim footprint for densely packed three-phase panels
- Direct three-phase input: 380-500 VAC with no neutral required, suited to 400 V and 480 V industrial mains
- High efficiency, low idle loss: 2.7 W at no load and 17.4 W at full load on 3x 480 VAC
- Fuse breaking current: typically 60 A for up to 12 ms to trip fuses and breakers on faulted output branches while the output stays above 20 V
- HiccupPLUS overload protection: automatic restart once the overload clears
- LED load bar: five-segment display shows output from >50% to >120% of rated power
- DC OK relay contact and LED for remote diagnostics
- Active inrush limiting: input current at turn-on stays below the steady-state level
- Wide temperature range: -40°C to +70°C operation
- 3-year PULS warranty

How Dynamic BonusPower Works
Instead of a fixed peak rating, the power supply monitors output through a power-time integral. The less extra power a load draws, the longer BonusPower stays available, and the supply recovers within seconds after a peak, so repeated motor starts and actuator cycles are supported without nuisance shutdowns.
| BonusPower Used | Available up to +45°C | Available up to +60°C |
|---|---|---|
| 110% | Continuous | 71.4 s |
| 120% | Continuous | 34.1 s |
| 150% | 15.8 s | 12.0 s |
| 200% | 5.0 s | 5.0 s |
Typical Applications
- 400 V and 480 V machine control panels without a neutral conductor
- OEM machinery and packaging lines where panel width is at a premium
- Panels feeding contactor coils, solenoid banks, and motor brakes with high short-term demand
- Semiconductor process equipment requiring SEMI F47 voltage sag immunity
- Outdoor and unheated enclosures down to -40°C
Approvals and Compliance
cULus Listed to UL 61010-2-201 (US and Canada), IEC 61010-2-201, IEC 61558-2-16 (Annex BB), 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.
- Keep 40 / 40 / 5 / 5 mm clearance (top / bottom / left / right), and 15 mm on the sides next to a heat source.
- Approved for branch circuits up to 30 A (UL) without additional protection. If an external breaker is used, choose 6 A minimum, B or C characteristic.
- Protective earth connection is required (Class I equipment). Do not operate with DC input.
- Can run continuously on two phases of a three-phase system with reduced output current. Two-phase operation is not covered by the UL approval.
