LED power supply voltage indicator measuring 3 x 400V with 1Z 6A 250V AC contact (WN-33P). The housing unit (17.5 mm) includes a device that signals the presence or absence of individual phases and provides information about the status of the three-phase network.

• Presence of correct voltage (-15% ÷ +10%): the average green diode lights up.
• Missing phase: the corresponding green diode turns off.
• Voltage below 195 V: the appropriate green LED turns off, and the left red LED lights up.
• Voltage above 253 V: the appropriate green LED turns off, and the right red LED lights up.
• Incorrect phase sequence: the lower left red LED with the phase rotation symbol lights up.
• Phase asymmetry above 5%: indicated by the lower middle yellow LED with the "ASY" indication.
• Phase short circuit: indicated by the lower right red LED with phase angle symbol.

Information transmission is done via 12 miniature, multicolored LEDs. The WN-33P features a galvanically isolated contact (6A 250V AC), which opens in case of any anomalies in the three-phase network, allowing for the transfer of failure information outside the device. The device parameters can be customized upon customer request.
