|GENERAL INFORMATION: |
The Bi-Polar “C” Series line of regulated DC-to-DC highvoltage converters is an extension of the High Power “C” Series. Bi-Polar “C” Series units contain a pair of + and - standard-product, 60-watt or 125-watt High Power “C” Series assemblies, providing a total of 125 watts or 250 watts. By encapsulating a module pair within one case, the cost of testing, potting, burn-in, and system integration is reduced.
The ± HV output pair is packaged in UltraVolt's 4.5" x 8" x 1.1" standard case. This high power density is especially suited to high-energy pulsers, amplifiers, and discharge devices with large capacitance, fast repetition rates, or high current loads. See Application Note 10 for more charging information. See the High Power “C” Series datasheet for detailed specifications.
The Bi-Polar “C” Series matches the standard UltraVolt 60 watt / 125 watt High Power “C” Series for all electrical functions and design methodology, including wide input range, remote control, enable/disable, output monitors, and local +5 VDC reference output.
HIGH VOLTAGE OUTPUT:
Bi-Polar “C” Series units, like all High Power “C” units, are non-isolated converters. The output range is independently adjustable from 0 to ±125V, ±250V, ±500V, ±1kV, ±2kV, ±4kV, or ±6kV on all 60Wx2 and 125Wx2 models. As the output voltage is reduced towards 0, the maximum current capability remains unchanged.
Internal capacitance is kept to a minimum to facilitate fastrise applications. Most fast-rise applications involve charging a storage capacitor, which also acts as an additional output filter/storage capacitor. If your application is continuous DC bias power, an external filter/storage capacitor should be added. Contact the factory for recommended capacitor values.
OUTPUT CURRENT & VOLTAGE MONITORS:
The Bi-Polar “C” Series units contain two pairs of output voltage and current monitors, one pair for the + HVPS, one pair for the - HVPS. See the High Power “C” Series data sheet along with Application Note 13 and Connection Drawings #3 and #4 for more details.
|HV & LV CONNECTIONS:|
Each independent HVPS in the Bi-Polar “C” Series has a dedicated input power and control connector. These connectors are standard, dual-row, 7-pin headers. Each HVPS also has a dedicated, HV-ground-return, 2-pin header and HV output, 2-pin header.
Wire-harness connections can be made via J-hooked and soldered leads, AMP Mod-U connectors with high-current pins, or other wire-applied header connectors.
PCBs can be mounted directly to HVPS with the headers plugged into PCB sockets or soldered directly to the PCB. Direct-mounted PCBs can use factory or user-supplied standoffs mounted directly to the (7) #4-40 & (4) #2-56 PEM nuts provided on top of the HVPS.
The Bi-Polar “C” Series converters are packaged in aluminum enclosures. Both the 125W(60Wx2) and the 250W(125Wx2) versions use the 38in³ package. Chassis wall mounting is facilitated with the four #8-32 studs. Thermal grease or elastomer should be used prior to mounting. An optional flush-mount bracket kit allows the unit to be surface mounted with the #8 studs removed. An optional vertical mounting bracket and finned heatsink allow the units to be stacked side by side.
The High Power Bi-Polar “C” Series provides full power at case temperature from -40 to +65°C. Extended temperature range is available along with enhanced capabilities. Please contact the factory. All units receive a 24-hour burn-in prior to final testing.
