Spellman MR Series, Instruction Manual

The MP Series has been designed as high performance
dc to dc converters with output voltages up to 40kV. 

Each module provides well regulated, low ripple and

high stability high voltage in a highly versatile compact
design, combining linear and switched mode techniques
to minimize internal dissipation and generated EMI/RFI
interference. The higher voltage modules are vacuum
encapsulated to ensure corona free operation.

Specialist cell manufacture of the MP Series ensures

prompt delivery.

SPECIFICATIONS

Input Voltage:

+24Vdc±2V. Other input voltages available on special order.

Input Current:

Less than 1A at full output.

Output Voltage:

Continuously adjustable over entire output range. Available
in either positive or negative output polarity. See table for 
voltage ranges.

Output Voltage Control: 

Controlled by either:

1) Internal ten-turn potentiometer
2) External potentiometer 5k to 100k (set internal pot. to max.) 
3) Remote differential voltage programming (0 to +10V gives

0 to full output).

Accuracy 0.1%.

Remote Control:

Remote programming Common Mode Range: -5VDC to +15VDC

Line Regulation:

0.001% for input change of 1V.

Load Regulation:

0.001% for 100µA to full load change
(at maximum voltage).

Temperature Coefficient:
