Delta Force-GT Series, Three-Phase DIN Rail Power Supplies for HVDC Rack Testing and AI Infrastructure


960 W Three-Phase DIN Rail Power for High-Demand Industrial and AI Test Applications

AI data centre infrastructure is driving rapid growth in HVDC rack power testing equipment. Power supplies used in this testing environment must handle demanding inrush conditions from capacitive and fan loads, deliver ultra-low ripple output across the full load range, and operate reliably in heavy industrial environments over long service cycles. Standard single-phase DIN rail supplies are frequently undersized for these requirements.

The Delta Force-GT three-phase DIN rail series addresses this directly. Available from 120 W to 960 W in a single slim DIN rail housing, the three-phase models accept 3-phase 320-575 V AC input (or 2-phase 340-575 V AC) and deliver 24 V DC output at efficiencies up to 94.5%. A -40°C cold-start capability and -25°C to +70°C operating range support deployment across heavy industrial and outdoor-rated enclosures. FORTEC Switzerland offers the Force-GT three-phase series as part of its Delta power supply portfolio.

Three-Phase Input for Industrial and AI Test Infrastructure

Single-phase DIN rail supplies are limited in the power levels they can deliver efficiently from standard industrial distribution. Three-phase input resolves this by drawing balanced current across all three phases, reducing per-phase current demand and enabling higher continuous output power from a slim DIN rail form factor. For HVDC rack test benches, semiconductor test equipment, and AI infrastructure verification setups, this makes the Force-GT 3PH the appropriate platform.

The four three-phase models cover 120 W to 960 W continuous from a single housing, all at 24.0-28.0 V DC adjustable output:

  • DRF-24V120W3GBA:120 W at 5.0 A; efficiency >87.5% at 400/500 V AC 
  • DRF-24V240W3GBA: 240 W at 10.0 A; efficiency >90.5% at 400/500 V AC 
  • DRF-24V480W3GBA: 480 W at 20.0 A; efficiency >94% at 400/500 V AC 
  • DRF-24V960W3GBA: 960 W at 40.0 A; efficiency >94.5% at 400/500 V AC

Ultra-Slim Form Factor for High-Density DIN Rail Installations

Despite the high power output, the Force-GT 3PH series maintains a slim DIN rail profile. The 960 W model measures 124 mm × 110 mm × 128.7 mm (H × W × D); the 120 W model 124 mm × 38 mm × 125.3 mm. This enables high functional density in control cabinet installations without the panel space required by conventional three-phase enclosed supplies.

Reliability Features for Continuous Industrial Operation

The Force-GT series incorporates long-life electrolytic capacitors and conformal-coated PCBs, supporting the extended service intervals demanded in industrial and infrastructure applications. A built-in DC OK relay contact provides direct power status monitoring for system supervisory logic without additional external components. Fast dynamic response and ultra-low ripple output maintain stable DC bus voltage under rapidly changing load conditions; a key requirement for test and measurement equipment where supply stability directly affects measurement accuracy.
