The field selectable input taps allow fine tuning the output voltage to match actual field conditions. The DC output is fused for short circuit protection. For maximum versatility, the output is floating and may be referenced to another low voltage common ground or placed in series with other DC power supplies. AC Input: 115/230VAC, 50/60Hz nominal. Field selectable taps for +/–10%. High line tolerance on voltage is +10% DC Output: Floating fixed output at full load ratings (see table). Transformer taps provided for approx. 10% output voltage adjustment. Ripple: 3% r.m.s. maximum at nominal line and full rated load. Operating Temperature: 0-50°C (Derate 2% per °C to 70°C) Overload and Short Circuit Protection: Fused output. It should be noted that the fuse is not necessarily direct in line with the output. In most models the fuse is prior to the output capacitor and in case of a short circuit, the capacitor energy will be discharged into the load even if the fuse has opened.

Motor and logic power supplies are both incorporated in one package (when applicable). Models are available to drive one or two motors. The single driver models are assembled on an L-shaped chassis and threaded (#6-32) PEM nuts to mount motor driver. The dual driver models feature a U-shaped chassis wire threaded (#6-32) PEM nuts on both sides to mount two motor drivers. This makes it an integral space saving unit eliminating the need for installing and wiring different pieces. Integral motor and logic power supplies The motor and logic power supplies required to operate the stepping motors and associated control logic are both incorporated in one unit. This eliminates the need to install and wire two different power supplies to a separately mounted driver modules. The motor power is unregulated DC voltage; while the logic power is a fully regulated DC output that is maintained within tight regulation (±0.25V) over a large range of input AC voltage. Models to drive one or two motors The single motor drivers are commonly used. However, in a multi-axis control application, the dual driver models are a very cost effective and space saving alternative. In the single as well as dual driver models, the voltage and current ratings are provided to allow maximum motor torque without exceeding the safe operating voltage and current limits. When operating two drivers from one power supply, the effect of regenerative energy must be considered to assure safe operation of the drivers. 20 Space saving compact power module provides mounting studs for motor drivers The StepperPower™ modules, series PV5000 and BVU6000, feature a transformer with high efficiency and excellent regulation that assures a compact physical size. They are assembled on space saving L- or U- shaped chassis. PEM nuts for mounting the driver modules are provided on one side of the L-bracket and on both sides of the U-chassis. Once the drivers are mounted on the power module, they become fully self-contained units without any need of external components. The outputs are lead wires that can be wired directly to the screw terminal connector available on the driver modules. This simplifies the installation and saves wiring time. Input taps to match actual line voltages As the motor power is unregulated, it tends to vary with the input line voltage. For example, if a high line is applied at the 120VAC tap, the motor output voltage may exceed the safe operating limit of the driver and cause damage. The taps are provided so that in high line locations, the output voltage can be kept within the safe operating limit by using the corresponding tap. The logic power is regulated and is not affected by the input line voltage over a wide range (95V AC to 135V AC when connected to 120V AC tap).
