Spellman MPD Series of High Voltage 10 Watt Modules
Spellman’s MPD series is a family of high voltage, high performance 10 Watt modules with output voltages ranging from 1kV to 30kV.
Spellman’s hybrid topology of linear and switch mode power conversion techniques delivers ultra-low noise, excellent ripple and stability performance all within itscompact footprint.
The MPD series can be controlled via analog or digital interfaces, both provided via a standard 15-pin D-type connector.
In analog mode, the unit features a differential amplifier input for the voltage programming signal to improve immunity from external system noise and address anyoffset issues. In digital mode, RS-232 and RS-485 interfaces provide additional features: current control, status flags, multiple units operation (RS-485 only), and wobbler function.
Spellman’s proprietary HV technology coupled with SMT circuitry results in an ultra-compact and lightweight module, available as either a positive or negative supply, that is ideal for OEM applications.
