The built-in display PCE-N20Z can be used to measure AC voltages up to 400 V and AC currents up to 5 A. The voltage to be measured is connected directly and can then be read on the 5-digit LED display of the built-in display. The display color of this built-in display can be in three colors depending on the measured value. The user can define the limits himself. This enables an assessment of the current measured value at first glance. The two open collector outputs can be used to monitor the voltage. If the limit values ​​are exceeded or not reached, the alarms are activated. The free LPCon software is available to configure the alarm limits and the limits for switching the display color. In addition to configuring the built-in display, this also enables an existing configuration to be read out. Once configurations have been created, they can be saved in a file and called up again from the same. This allows multiple built-in displays to be configured with the same settings. The built-in display is connected to the PC using the optionally available programming adapter PCE-PD14, which converts the data stream and sends it to a USB port on the computer. The built-in display is available in two versions, which differ in the power supply (230 V or 24 V).
