Manufacture of metal products. Mechanical engineering and plant engineering, general. Motor protection relays also available in the most compact type: Frequency relays System monitoring when power is fed in the system,e. Comply with specific norms, e. More information The voltage and frequency monitors from DOLD are the optimal solution for grid monitoring during energy input into the public grid. IKIK Undervoltage relay for medical areas acc. Looking for specific product information?
If one system phase fails, electrical drives can run on, but they can no longer xold or restart. Monitor for neutral conductor interruptions to protectconnected devices, e.
Work on the principle of frequency comparison: Multifunctional relays Critical monitoring functions integrated in a single compact device, e.
Metallic isolation from rp9800 system: Customers benefit from DOLD’s complete functional range. Load monitors, overload monitors, load transformers Load relays monitor the active-power input of electrical loads.
Used in manufacturing lines, materials handling, packing machines, filling plants or r9800 mills, for example. Undervoltage and overvoltage relays, voltage doldd and three-phase: LEDs on the front provide visual status indications. As the phase angle changes with the motor load this measuring method is suited for monitoring asynchronous motors for underpower and no load operation independent of their size.
The measured frequency is compared with a frequency generated in the device and settable on a setting knob. Monitor single- and three-phase asynchronous motors undirectionally for underpower and no-load operation, e. Unbalance relays, phasemonitors, phase indicators Monitor motors in three-phase systems to prevent reversing andsingle-phase operation and consequences of this.
BAAI Save space, wiring expense and dod by integrated straight-through current transformer in our CT range.

Ensure the start ofthree-phase motors in the correct sense of rotation, e. Universal use for resistance measurements. Underpower monitors Underpower relays monitor the phase angle between current and voltage.
Sale, maintenance and repair of motor vehicles. DOLD monitoring and measuring relays are used in all industrial areasand in a variety of applications. Because of its measuring principle this product can also be used for general resistance monitoring. The single-phase measuring principle assumes a symmetrical load in all 3 phases as is common with motive-powered loads. Output contacts Module translation not found: Voltage and frequency monitor. As electrical machines partly regenerate such a missing system phase only an unbalance relay can detect such a case.
Some application examples for the differentdevice groups are mentioned below: Choice of two outputs for min. Measuring relay for specfic applications Special-purpose applications, e. Manufacture of clothing, except fur clothing. IKSK Wide Signal Measurement Range Suitable for use with all types of 1 e The RP monitors the voltage of the 3 phases against neutral indicating over and undervoltage.
Load monitors, overload monitors, load transformers Used in manufacturing lines, materials handling, packing machines, filling plants or crushing mills, for example. Manufacture of other special purpose machinery.
