VPP28 –180

Electrical Specifications (@25C)

1. Maximum Power: 5.0VA

2. Input: Series: 230VAC, 50/60Hz; Parallel: 115VAC, 50/60Hz

1 2

4. Voltage Regulation: 25% TYP @ full load to no load

5. Temperature Rise: 30C TYP (45C MAX allowed)

6. Insulation Resistance: 100M ?

7. Hipot: 4000VAC between primary to secondary and windings to core.

Construction:

Dual bobbin construction with an insulated shroud, both made of a high temperature material that exceeds

UL flammability requirements.

Safety:

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:
