When the spin wheel is rotated more rapidly the rate of increment is increased, enabling the value to be changed quickly. The action of the spin wheel can be changed from System Preferences to reduce the speed-related increment rate if preferred.

    See ‘Technical Specifications’ for accuracy specifications. On the MX100Q/P model, ranges 16V and 35V offer greater resolution and accuracy than 70V range and uses 5-digit meters to give 1mV and 0.1mA resolution (as against 10mV and 0.1mA for 70V range).

  • Page 26: Parallel Wiring Of Outputs

    8 - Notes on Operation Parallel Wiring of Outputs If currents above 6 amps are required, this can be achieved by wiring two or more outputs in parallel. For example, outputs 1 and 2 could be paralleled to provide 16V/12A. In this situation it would be appropriate to use voltage tracking (Mode1 V2=V1 in this example) so that the voltage can be adjusted directly on one output.

  • Page 27: Series Wiring Of Outputs

    For example, outputs 1, 2, 3 and 4 could be series connected to provide up to 140V. If using the MX100Q/P model, Voltages up to 140V can also be achieved by connecting outputs 3 and 4 in series and selecting voltage tracking so that full voltage adjustments can be made using one output control.

  • Page 28: Instantaneous Current Output

    8 - Notes on Operation Instantaneous Current Output The current setting control can be set to limit the continuous output current to levels down to the milliamps. However, in common with all precision bench power supplies, a capacitor is connected across the output to maintain stability and good transient response. This capacitor charges to the output voltage and short-circuiting of the output will produce a current pulse as the capacitor discharges which is independent of the current limit setting.

  • Page 29: Using Ovp And Ocp

    8 - Notes on Operation Using OVP and OCP OVP (over-voltage protection) monitors the voltage on the output terminals and switches the output off if it exceeds the OVP setting. The response speed is typically 100us. Control of OVP is described in ‘Setting Over-Voltage and Over-Current protection’. OVP might be used to guard against accidental mis-setting of the power supply or might be used to identify a fault condition when operating in constant current mode.
