Incorporating a custom inte- 3 3 EN 55022, Class B FCC Part 15, Class B grated circuit into a small package (2.45 in 40.1 cm ) the BIAS Meets UL/CSA and EN Product Safety (ITE) Module provides an immediate drop-in solution, requiring no additional external components. Bias Power AC/DC power supplies are designed to be applied in two major categories of applications Operating Specifications ( 120VAC / 60 Hz / 25C unless otherwise specified) Auxiliary, where the Bias supply is one of two or more sup- plies and provides power for standby, housekeeping, bias- Electrical ing or other requirements. Generally, these supply 3.3V or Input Voltage Range 85 - 308 VAC (50/60Hz) 5.0V requirements from the Vr output. In some cases a small amount of Vo power is used.

The graceful transi- No-load Consumption 30 mW typical Vin=120 VAC tion from voltage regulation to constant power along with the wide range of product ratings, allows the designer to Isolation 3000 VAC (meets UL / CSA & EN Product Safety) select a supply tightly matched to the design load.
