Single-phase digital voltage indicator PH-11 NTRN11000

Digital single-phase voltage indicator PH-11

This device is manufactured by Novatek Electro and designed for precise measurement and display of voltage values in single-phase networks. PH-11 is an indispensable element for monitoring electrical installations, finding application in switchboards, distribution boards, as well as in industrial and domestic installations. Quick and accurate voltage assessment translates to the safety and reliability of the entire system.

Application and functionality

This indicator is particularly useful in situations where voltage stability is critical for the proper operation of connected devices. It allows for continuous monitoring of network parameters, which minimizes the risk of damage caused by voltage fluctuations. Mounting on a 35 mm DIN rail (2 modules) facilitates integration with existing electrical infrastructure. The device is equipped with a clear, three-digit LED display, which ensures easy reading of the voltage value.

Construction and parameters

PH-11 is characterized by a solid construction and high quality workmanship. The housing with dimensions of 90x36x59.5 mm provides adequate protection against external factors (protection degree IP20 on the terminal side, IP40). The device operates in a wide temperature range from -30°C to +55°C, which guarantees its reliability in various environmental conditions. The maximum voltage at which the indicator maintains proper operation is 450V, and the power consumption is a maximum of 3.5W. It has 8 terminals for connecting phase (L) and neutral (N). The use of LEDs as a display element ensures good visibility of the indications even in low light conditions.
