This low-cost supply provides up to two watts of output power at 8 or 14 VDC (Vo) and an optional 3.3 or 5 VDC (Vr) output for logic functions such as a microprocessor, logic, timing circuits, transceivers or sen- sors. A patented design incorporating a custom integrated circuit into a small package (0.87 in 3 [14.3 cm3]) the BIAS Module provides an immediate “drop-in” solution, requiring no additional external com- ponents.

Generally, these supply 3.3V or 5.0V requirements from the Vr output. In some cases a small amount of Vo power is used. Second is as a main or utility supply where Bias is the only supply and provides all power necessary for the product or system. Both Vr and Vo supplies are often utilized for opti- mum system performance. The characteristics of the Vo and Vr outputs are different and each has application-specific benefits which can pro- vide high value to the system designer. Vo is a voltage-regulated output which has a constant power mode instead of a conventional current limit. This output is best suited to drive mechanical relays, solenoids, SSRs, capacitive loads, indicating lights, LEDs and as a source for isolated DC utility power which may be used directly or post-regulated with either a linear regulator or a DC/DC converter. Vo is self protecting, cannot be over- loaded and can be shorted indefinitely. The graceful transi- tion from voltage regulation to constant power along with the wide range of product ratings, allows the designer to select a supply tightly matched to the design load. There is no need to oversize a Bias Power supply. Unlike design- your-own, or partially complete modules where significant design margin is required, to stay far away from current limit, Bias’s constant power alternative requires no such over-spec’ing. Vr is also a voltage-regulated output and is thermally pro- tected from overload. It has very low output ripple capable of driving microprocessors , logic, sensors, transceivers and other elements which require a low-noise, tightly-regulated supply. In addition, Vr is supplied internally by Vo. This means that any capacitance added to Vo can increase the hold-up time of Vr as well. *Note: maximum currents specified for constant voltage range only. See V-I curve on page 2 for Vo in constant power range. |
