Voltage Monitoring Relays, Single Phase

Novatek Electro (India) Pvt Ltd offers a range of single phase Voltage Monitoring Relays. These are used for the protection of single-phase loads, equipment and machinery against un-allowable mains voltage drops and fluctuations as well as against the consequences of neutral line cut-off. They can be utilized either as independent switching devices, or as relays operating with a magnetic starter (contactor). Advantages of the relays are wide voltage operation range and broad range of adjustable parameters, including auto reclosing time delay settings for the protection of machinery and installations with long-term transient dynamics, like refrigeration and compressor units. Model RN-111M features the newest modification of a panel board mounted single phase voltage protection relay. Besides the principal dedication of protecting load against voltage surges in the mains, it provides a number of additional functions: multifunctional digital display; and operation mode selection by dipswitch. Novatek-Electro Ltd was established in one of the major Ukrainian port cities – Odessa with 100% Ukrainian capital. The company consists of highly experienced specialists in the field of engineering in microprocessor based devices as well as engineers of control and safe operation of all types of electric circuits and power systems. Some of the products by Novatek-Electro Ltd have no analogues and could be considered at the level of scientific discoveries.
The relay incorporates functions of 5 complete devices in one compact case:

• Combined over/under-voltage protection relay with separate setting of minimal and maximal thresholds
• Minimum voltage protection relay
• Maximum voltage protection relay
• Protection from the consequences of neutral phase loss
• Time delay – auto reclosing after the fault with user defined time delay (protection from frequent starts or nuisance tripping)
• Compact overall dimensions – 2-way width casing.
