I/O power supply module A7512DB

Single Desktop HV channel 0 ÷ 12 kV output voltage 20 μA maximum output current Available with positive or negative polarity LEMO HV output connector 200 mV voltage monitor resolution 500 pA current monitor resolution Digital output voltage control Internal memory for permanent storage of calibration and configuration RS485 digital control (allows to build daisy chain network of A75xxDB modules) LEMO 00 connector for preamplifier power supply Interlock logic for Module enable SMART HV command interface Overview The A7512DB Power Supply Module is a compact desktop 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 with 200 mV monitor resolution The maximum output current is 20 μA, with 500 pA monitor resolution. It is available with either positive or negative output voltage. HV output is delivered through LEMO HV connector. The following channel parameters can be programmed Output voltage: 0 ÷ 12 kV step: 200 mV Current limit 0 ÷ 20 μA step: 1 nA Voltage Ramp up/down: 1 ÷ 500 V/sec step: 1 V/sec TRIP parameter 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). Safety features include: Overcurrent detection: if the channel attempts to draw a current larger than Iset, the output voltage is automatically adjusted to keep the current below Iset limit.
