MRB Series

Product catalog summary

Introduction
The Wisman MRB series consists of modular high-stability precision high-voltage power supplies. These modules offer excellent regulation performance and provide either unipolar or bipolar high voltage outputs. The maximum voltage for singular high voltage output is 70kV with a power of 280W, while bipolar outputs can reach up to 140kV (±70kV). The MRB series can be monitored and controlled internally, externally, or via computer precision measurement, with RS-232 and RS-485 digital control interfaces available. Safety features include over-voltage/current protection and a safety interlock.

Typical Applications
The MRB series is suitable for high voltage testing, electrostatic discharge tests (ESD), electrostatic chucks (ESC), electron and ion beams, high voltage bias, hi-pot testing, electrospinning, capacitor charging, semiconductor testing, electronic component aging, electric power cable testing, and various scientific, laboratory, chemical, and industrial applications.

Specifications
The MRB series offers output voltages ranging from ±10kV to ±70kV with power outputs between 100W and 280W. The ripple is ≤1% rms for frequencies over 20kHz and 0.1% rms for frequencies under 20kHz. Stability is rated at 25ppm/hr after a 2-hour warm-up period. The temperature coefficient is ≤25ppm/°C. Voltage and current programming can be done locally or remotely, with load and line regulation at 0.01%. Operating temperatures range from 0°C to +40°C, with storage temperatures from -40°C to +85°C. Cooling is achieved through free convection for power ≤100W and fan-assisted for power ≥100W.

Selection and Customization
The MRB series offers various models with different voltage and power specifications. Customization options are available, including OEM customization. The series supports RS-232 and RS-485 digital interfaces for enhanced control and monitoring capabilities.

Safety and Protection
Safety features include arc, over-voltage, and short-circuit protection. The modules also feature a safety interlock to ensure safe operation.
