This family is a line of low noise, single channel High Voltage DC/DC converters (up to 12 kV) in a compact and easily mountable form factor. In the astroparticle research field, in which large area experiment composed by detectors spread over a very large area are involved, the traditional multichannel approach become unfeasible and the necessity of a distributed solution become unavoidable.
This familiy provides a solution to these kind of needs without giving up to high performances and to the reliability of a remote control (analog or digital). With their high efficiency in a compact form factor these modules are suitable for large area experiments or embedded application.
Four models are currently available: A7505B, A7501B, A7512DB, A7526DB, supplying up to 1600V/500µA, 2100V/100µA, 12000V/20µA, 2600V/500µA respectively. Each module can be provided with either positive or negative polarity.

Single Channel High Reliability, High Voltage Power Supply Boxes Models
A7501B and A7505Bare solution designed for operating in challenging environmental conditions and high thermal excursions. They rely on the high efficiency PCB High Voltage power supply A7501 / A7505 embedded in a custom carrier, providing up to 1600V/500µA (A7501B) or 2100V/100µA (A7505B).
In order to assure its functionality for long working periods under severe environmental conditions, several dedicated technical and electrical precautions have been implemented such as stress relief techniques on cabling and soldering points, electrical redundancies, PCB layout design, and use of specific materials to minimize the thermal expansion on PCB and housing mechanics.
These features make A7501B / A7505B boxes ideal for Large Area experiments where the possibility of a prompt maintenance intervention is reduced.
Temperature working range: -10°C ÷ 70°C
Designed for long working life in harsh environment
Assembly optimized for easy maintenance operation
A7512DB
The A7512DBPower Supply Module is a compact solution to provide stable and noiseless power supply for single and multi-gap Resistive Plate Chamber (RPC) detectors.
The module houses a digital controlled high voltage channel that provides a 12 kV maximum voltage and 20 μA maximum current. It is available with either positive or negative output voltage. HV output is delivered through LEMO HV connector.
Power supply control can be performed remotely, via RS485, that allows to build a daisy chain network of A75xxDB modules.
A7512DB houses also bias output through LEMO 00 connector for preamplifiers power supply. Three different options are available: 2.8 V / 3.3 V / 5 V (maximum output power: 3 W).
A7526DB
The A7526DBPower Supply Module is a compact desktop solution to provide stable and noiseless power supply for several kinds of detectors.
The module houses a digital controlled high voltage channel that provides a 2.6 kV maximum voltage with 100 mV monitor resolution The maximum output current is 500 μA, with 10 nA monitor resolution. It is available with either positive or negative output voltage. HV output is delivered through SHV connector.
