The Vanguard UPS S3 is an AC/DC adjustable output power supply designed to operate substation circuit breakers. The UPS S3’s AC and DC voltage sources can supply up to 10 Amperes during the circuit breaker coil energization and circuit breaker charging motor operation.
Powered by a single phase 90-120 Vac voltage source, the UPS S3 provides an isolated adjustable AC/DC voltage source. Output voltages are variable via the front panel control knob.
The unit’s variable AC output voltage source (10-140 Vac) is rated at 140 Vac @ 9A continuous. It is also full-wave rectified and filtered to provide an isolated DC voltage source. The DC voltage source (10-200 Vdc) is rated at 180 Vdc@9A (2 seconds) or 180 Vdc @ 2A continuous. Both AC/DC voltage source outputs are protected by a circuit breaker.
A built-in dual volt meter displays both AC and DC voltage simultaneously on a back-lit LCD screen (128 x 64 pixels) that is viewable in bright sunlight and low light levels. Both AC and DC voltage displays range from 0-200 Vrms.
The UPS S3 is housed in a plastic enclosure (17.5” x 12.5” x 11.7”) and weighs 45 lbs. (20.4 Kg). A power cord, safety ground cable and voltage connection leads are included.

Vanguard UPS S3是一种AC / DC可调输出电源，设计用于操作变电站断路器。在断路器线圈通电和断路器充电电机运行期间，UPS S3的交流和直流电压源可提供高达10安培的电流。
UPS S3由单相90-120 Vac电压源供电，提供隔离的可调AC / DC电压源。输出电压可通过前面板控制旋钮变化。
该装置的可变交流输出电压源（10-140 Vac）额定电压为140 Vac @ 9A。它还经过全波整流和滤波，以提供隔离的直流电压源。直流电压源（10-200 Vdc）额定电压为180 Vdc @ 9A（2秒）或180 Vdc @ 2A连续。两个AC / DC电压源输出均由断路器保护。
内置双电压表可在背光LCD屏幕（128 x 64像素）上同时显示交流和直流电压，可在明亮的阳光和低光照条件下观看。交流和直流电压显示范围均为0-200 Vrms。
UPS S3安装在塑料外壳（17.5“x 12.5”x 11.7“）中，重45磅。（20.4公斤）。包括电源线，安全接地电缆和电压连接引线。
