MCP4 Model | High Voltage DC DC Converter

Spellman’s MCP4 is a well-regulated, high performance DC-DC converter featuring a floating 4kV @ 600uA output, isolated to 15kV. The MCP4 low output ripple specification and high stability make it ideal for use with detectors in Mass Spectrometry applications such as: Electron Multipliers (EM’s), Microchannel Plates Detectors (MCP’s) and Channel Electron Multipliers. This module is packaged in a shielded metal enclosure and the high voltage output is provided via two captive one meter long shielded coaxial cables. The unit has remote 0-10Vdc = 0-100% rated voltage programming and voltage monitor. A TTL compliant Enable signal provides simple control of the high voltage output. This unit has specifically designed to minimize crosstalk with the high voltage source which it is floated upon. The MCP4 can be customized to meet OEM requirements.

Typical Applications:

• Mass Spectrometry Detectors
• Microchannel Plates
• Electron Multipliers
• Channel Electron Multipliers

Input Voltage:

+24Vdc, ±5%

Input Current:

700 mA maximum

Output Voltage:

0 to 4kV, continuously variable over the entire output range

Output Current:

600uA maximum

Current Limit:

1900uA maximum

Polarity:

Reversible polarity inherent by design

Isolation Voltage:

Up to 15kV total to ground.
Note: When the unit output is set to zero and no load is connected: If the reference supply is positive (up to +15kV), +VE will always be less than 100V with respect to -VE. If the reference supply is negative (up to -15kV), a 47MΩ pre-load resistor fitted within the MCP4 limits +VE (with respect to -VE) to ≤ 1400V

Line Regulation:

50ppm for a ±5% line change

Load Regulation:

300ppm for a 10% to 100% load change

Voltage Programming:

0 to 10 volt corresponds to 0 to 100% of rated output voltage

Voltage Monitor:

0 to 10 volts corresponds to 0 to 100% of rated output voltage. Accuracy ±1%. Iout=300μA maximum
