At Powerbox, we stock and support a wide range of Delta DIN rail power supplies in New Zealand and Australia, suited for industrial environments such as automation systems, machine building, switchboard construction, control systems, and security infrastructure. A common question we hear from engineers and procurement teams alike is:
“Which Delta power supply series is right for my application?”
To help answer that, we’ve developed a simple comparison guide covering Delta’s three core DIN rail families: Chrome, Lyte II, and Force GT.
Whether you’re designing a compact control panel or specifying a high-performance power supply for demanding industrial applications, this guide will help you select the right model suitable for the job.
The Delta Din Rail Series Explained
Chrome Series
Delta’s Chrome series is designed for basic, cost-conscious applications where space is at a premium. With its Class II design (no earth connection required), double insulation, and ultra-compact plastic housing, the Chrome series is ideal for use in building automation systems, light-duty control panels, access control, and small enclosures. While feature-light by design, it delivers the essential performance needed for stable DC output, ease of installation, and long service life in non-critical environments. Installers benefit from simple DIN rail mounting and universal AC input, making it a solid choice for high-volume OEM or budget-limited projects.
Lyte II Series
The Lyte II series strikes a well-calibrated balance between affordability and industrial-grade functionality. Engineered for switchboard builders, machine OEMs, and general industrial automation, Lyte II power supplies offer higher efficiencies (up to 89%), wider operating temperature ranges, and slim metal housings designed to save valuable cabinet space. Key features include constant current mode for reactive loads, full output power up to 50°C (derated above), and broad international certifications (including SEMI F47 and UL 508), making this series suitable for most factory floor and infrastructure environments. It’s the ideal go-to platform for engineers seeking a reliable, cost-effective industrial PSU.
Force GT Series
Delta’s Force GT series is purpose-built for high-performance industrial environments, where reliability, resilience, and power density are paramount. It delivers industry-leading efficiency (up to 95%) in an ultra-slim metal enclosure, with features including DC OK relay output, wide input voltage ranges (including three-phase options), and conformal coated PCBs for enhanced protection in dusty, humid, or corrosive environments. Suited for automation control cabinets, semiconductor manufacturing, renewable energy systems, and industrial robotics, Force GT provides a robust foundation for critical systems that must operate 24/7 with minimal margin for failure at a competitive price point.

Which Delta Din Rail Series is right for you?
Choosing the right power supply isn’t just about voltage and current, it’s about aligning performance, reliability, and cost with the demands of your application. Here’s how each Delta series compares:
-
Chrome Series
A smart choice for compact and cost-driven installations where simplicity and space efficiency matter. Ideal for basic control loads in building automation, access control, or small-scale industrial panels.
-
Lyte II Series
The reliable all-rounder for general industrial use, offering high efficiency, slim DIN rail mounting, and excellent value. Perfect for machine builders, switchboard manufacturers, and system integrators who need dependable performance without over-specifying.
-
Force GT Series
Designed for high-performance industrial applications, Force GT delivers exceptional efficiency, wide operating temperature tolerance, and a compact footprint, all at a price point that compares very favourably to premium brands commonly used in industrial automation, including PULS, Phoenix Contact, Weidmüller, Omron, Siemens, and Rockwell. It’s an excellent fit for automation systems, process control environments, and applications requiring higher output power or rugged reliability.
