PULS QT20.481 3-Phase DIN Rail Power Supply
Description
Original PULS DIMENSION QT20.481 48V 10A Three-Phase DIN Rail Power Supply for System Ceramic Inkjet Printers
Ultra-Efficient 480W Industrial 48V DC Power Unit with BonusPower for Ceramic Tile Digital Printing Systems
The PULS QT20.481 is a top-tier German-engineered 480W three-phase industrial DIN-rail power supply from the renowned PULS DIMENSION Q-Series. Designed to deliver clean, highly stabilized 48V DC power with an industry-leading efficiency of up to 95.3%, this unit is widely adopted as an essential electrical replacement and OEM part in System ceramic inkjet printers and high-speed digital tile printing production lines.
With its ultra-compact 65mm width, 3-phase wide input capability (380 to 480VAC), and integrated 125% BonusPower (600W reserve), the QT20.481 provides uncompromising reliability for sensitive printhead driver boards, industrial servo motors, ink heating systems, and high-frequency motion controllers in tough ceramic plant environments.
Key Features and Advantages
- Dedicated Compatibility for System Ceramic Printers: Engineered to match the exacting electrical standards of System digital tile inkjet printers, ensuring zero system disturbance and maximum line uptime.
- High Efficiency up to 95.3%: Minimizes internal heat generation and energy waste, dramatically extending component lifespan even in non-air-conditioned factory cabinets.
- Extra Power Reserve (BonusPower 125%): Supplies up to 600W (12.5A at 48V) for 4 seconds to easily handle peak inrush currents from ceramic printer servo motors and solenoid valves without voltage drops.
- Ultra-Compact 65mm Slim Housing: Exceptional power density frees up valuable mounting space on standard DIN rails inside crowded electrical control enclosures.
- Wide 3-Phase Input (380 to 480VAC): Operates reliably with 3-phase or 2-phase input, featuring active inrush current limitation to prevent nuisance breaker tripping upon power-up.
- Robust Ceramic Plant Durability: Convection cooled without moving fans, offering superior protection against glaze dust, fine ceramic powder, and electrical interference (EMC).
- Advanced Diagnostics and Safety: Equipped with DC-OK relay output, overload protection (choice of continuous current or latch-off mode), and complete overvoltage/overtemperature shutoff.

Frequently Asked Questions (FAQ)
Q1: Can the PULS QT20.481 directly replace the original power supply on a System ceramic inkjet printer? A: Yes. The PULS QT20.481 is a standard factory-installed or drop-in replacement 48V power unit used in System ceramic digital printers. It mounts onto standard 35mm DIN rails and connects directly to existing 3-phase wiring terminals without mechanical alterations.
Q2: What is the benefit of the PULS BonusPower feature in ceramic printing? A: During rapid print carriage acceleration or high-power ink heating cycles, components can draw brief current spikes. The 125% BonusPower (600W for 4s) ensures these surges are absorbed cleanly without triggering protection shutdowns or causing printhead voltage drops.
Q3: Does the QT20.481 require an external cooling fan in hot ceramic manufacturing plants? A: No. Thanks to its remarkable 95.3% efficiency, the unit dissipates minimal waste heat and relies entirely on natural convection cooling, making it completely fanless and immune to ceramic dust clogging.
