Industrial Control Transformer .050 kVA, 240 X 480 Primary Volts

The .050 kVA transformer provides a compact solution for converting 480 V to 240 V in control panels and equipment enclosures. Its epoxy-encapsulated design protects the core and coil assembly from contaminants, while silicon steel laminations reduce core losses and improve efficiency for steady operation at 50/60 Hz.
Industrial Control Transformer .100 kVA 240 X 480 Primary Volts

This 0.1 kVA transformer expands capacity for slightly larger loads while maintaining the same primary/secondary voltages. Epoxy encapsulation guards against contaminants, and silicon steel laminations help minimize losses at standard industrial frequencies.
Industrial Control Transformer .050 kVA With Secondary Fuse Clips

This variant adds secondary fuse clips for protection and easier integration into control circuits. Epoxy encapsulation and quality silicon steel laminations maintain efficiency and reduce heat buildup during operation at 50/60 Hz.
Industrial Control Transformer .500 kVA 240 X 480 Primary Volts

Designed for larger loads, this 0.5 kVA transformer maintains efficiency with epoxy encapsulation and silicon steel laminations. A robust primary block and secondary fuse clip configuration supports reliable operation in demanding environments.
Industrial Control Transformer .150 kVA 240 X 480 Primary Volts

At 0.15 kVA, this transformer balances compact size with greater output capability. It features a factory-installed 2-Pole Primary Block and secondary fuse clips, with epoxy encapsulation and silicon steel laminations to support efficient 50/60 Hz operation.
Industrial Control Transformer .300 kVA 240 X 480 Primary Volts

For higher-demand control circuits, the .300 kVA option provides scalable power with a solid construction. The integral 2-Pole Primary Block offers straightforward installation and compatibility with standard 120 V secondary options when available in designs requiring a 120 V output.
Industrial Power Transformer 240 X 480 Primary 120 X 240 Secondary

This Siemens transformer provides a domestic option for 240 x 480 V primary to 120 x 240 V secondary conversion. It emphasizes efficiency with a silicon steel-laminated core and copper magnet wire, suitable for steady industrial use at 50/60 Hz.
Industrial Control Transformer .200 kVA 240 X 480 Primary

This .2 kVA option suits mid-range loads with a robust 240 x 480 to 120 x 240 configuration. Epoxy encapsulation and silicon steel laminations help minimize energy losses, while a factory-installed 2-Pole Primary Block and fuse clips simplify installation in control panels.
Buying Guide: Key Purchase Considerations
- Voltage and power rating: Ensure the primary and secondary voltages match your system (480 V to 240 V) and choose a VA rating that meets or exceeds load requirements.
- Efficiency and losses: Look for silicon steel laminations and epoxy encapsulation to reduce core losses and protect against contaminants.
- Protection features: Secondary fuse clips, primary blocks, and enclosure protection affect safety and ease of integration in control panels.
- Frequency compatibility: Most are rated for 50/60 Hz; confirm your application’s frequency to avoid performance losses.
- Mounting and enclosure: Factory-installed blocks simplify mounting; verify footprint and enclosure compatibility with your panel design.
- Maintenance considerations: Epoxy encapsulation reduces exposure to humidity and dust, improving longevity in harsh environments.
- Brand and availability: Reputable brands with readily available replacement parts can reduce downtime in critical applications.
- Cost vs. capacity: Higher VA units offer headroom for future expansion; assess current loads and future needs to avoid under- or over-sizing.
