(manual control). Signals for the control of the resonance converter and the stabilizer circuit are derived from the result of the comparison. The two-stage layout of the control circuit results in an output voltage, stabilized with very high precision to the set point. SHQ series |Last changed on: 04.07.2017| www.iseg-hv.com 6/16... -

The SHV connectors are mounted isolated to chassis (PE) in order to have a floating HV-0V. If the floating voltage is increased above 47V a suppressor diode connects HV-0V to PE (chassis) to avoid dangerous voltages between HV-0V and PE/chassis.

2 line LCD display. Voltages and / or currents are displayed with the resolution of voltage- and current measurement of the corresponding SHQ series device. The polarity of the output voltage is also indicated. 3.2.2 Remote control (“CONTROL” in lower position) If the CONTROL switch is in lower position (DAC), high voltage will be activated only after receiving corresponding RS232 commands. -
