Overview
The Sola Hevi-Duty HS19F500B is a proven buck-boost transformer designed for industrial automation and control power applications. 500 VA, 1-Phase, 120 x 240 Primary Volts – 12/24 Secondary Volts, Buck-Boost Transformer, Non-Encapsulated, Indoor/Outdoor, 50/60Hz. This model provides an energy-efficient, low-cost solution for voltage regulation in control panels, lighting systems, and automation equipment where small voltage adjustments are required.
Key Features
- Small, single phase, dry type distribution transformer designed as insulating/isolating transformer with dual voltage primary and dual voltage secondary
- Used to power control panels, landscape lighting and other loads with specific voltage requirements that differ from the available line voltage
- Buck (lower) or boost (raise) the supply voltage a small amount, usually 5 to 27%
- Low cost, compact size and light weight
- Can be connected for a wide range of voltage combinations
- When connected as an autotransformer, can handle loads up to 20 times the nameplate rating
