POWE R TRAN S FO R M E R
CHASSIS MOUNT :
QUICK-CONNECT WORLD SERIES ?
VPS28-6250
Electrical Specifications (@25C)
1. Maximum Power: 175.0VA
2. Primary – Series: 230VAC, 50/60Hz; Parallel: 115VAC, 50/60Hz
3. Secondary: - Series: 28.0V CT@ 6.25A; Parallel: 14.0V @ 12.5A
4. Voltage Regulation: 25% TYP @ full load to no load
5. Temperature Rise: 30C TYP (45C MAX allowed)
6. Insulation Resistance: 100M ?
Construction:
Dual bobbin construction with an insulated shroud, both made of a high temperature
material that exceeds UL flammability requirements.
Safety:
These units are designed with 4000VAC isolation between the primary and
secondary, and also, between each winding and the core. Since the dual bobbin
construction effectively reduces capacitance, electrostatic shielding is not required.
World Series Transformers are designed and manufactured to meet the following
agency approvals:
