These type QL transformers have passed the UL K-factor testing program. K-factor is a unit measuring a transformer’s ability to withstand the harmonics content of a system. GE offers K=4, K=13, K=20 and K=30 transformers.
Applications
- K=4– Welders– Induction heating– HID lighting– Fluorescent lighting
- K=13– Telecommunications equipment– Classroom facilities– Healthcare facilities– Production lines– SCR variable speed drives
- K=20– Office buildings– Data processing equipment– Adjustable speed drives– Computer installations– Instrumentation
- K=30– Computer installations– Office buildings– Data processing equipment– Adjustable speed drives– Instrumentation
Features and Benefits
- K-Factor rated for nonlinear loads
- UL listed
- Complies with DOE-2016 efficiency standard
- Full-width copper electrostatic shield standard
- 200% neutral standard
- Effective coupling capacitance 30pF
- Common mode noise attenuation 120dB
- Normal mode noise attenuation 30dB
- Available in 150C, 115C, 80C and low-noise models
- NEMA 2 powder-coat drip-proof enclosure is standard. Weathershield kit is available for conversion to NEMA 3R outdoor
- NEMA 3R stainless steel enclosure is available up to 150kVA . To specify a stainless steel enclosure for an aluminum transformer, substitute an “S” in the fifth character in the GE catalog number. Example 9T14A1001G03 changes to 9T14S100G03. To specify a stainless steel enclosure for a copper transformer, substitute an “Z” in the fifth character in the GE catalog number. Example 9T14C1004G03 changes to 9T14Z1004G03.
