DT651H63S - SolaHD 63KVA 460D-460Y SCR DRIVE
For SCR (Silicon Control Rectifier) variable speed motor drive applications, a transformer is needed to magnetically isolate the incoming line from the motor drive. The transformer must also provide a voltage change to match the required voltage of the SCR drive. Standard designs are delta primary and wye secondary to match the common power sources required in most three phase rectifier circuits. Drive isolation transformers are specifically designed to handle the mechanical stresses, voltage demands and harmonics associated with SCR applications.
Applications
- SCR variable speed drives
Features
- Isolation minimizes load disturbances caused by the SCR drive
- UL Listed, NEMA type 3R enclosure is available when used with optional weather shield
- Taps on all units for adjustments to incoming source voltage
- Full capacity secondary neutral as required by the National Electrical Code
- Shielding attenuates line to ground noise

Major advantages of buck-boost transformers include compact size, light weight and suitability for outdoor use. They are also more efficient and cost less than equivalent isolation transformers.
When a buck-boost transformer has the primary and secondary windings connected according to the recommended instructions, it becomes an autotransformer. In this configuration, only the secondary windings transform voltage and current. The majority of the kVA load passes directly from the supply to the load. This allows buck-boost transformers to handle kVA loads up to 20 times the nameplate rating. Buck-boost transformers comply with NEC Article 210-9, Exception 1 when field connected as an autotransformer.
Applications
- Ideal for low voltage applications such as landscape lighting and control panels, buck-boost transformers are small, single phase, dry type distribution transformers designed and shipped as insulating/isolating transformers.
