iso685-S BENDER

iso685-S BENDER Power module

Product  Description：

The iso685-S belongs to the ISOMETER family and is a multifunctional device that monitors insulation resistance in AC, AC/DC, and DC systems. It is engineered to handle modern power systems that utilize frequency converters, rectifiers, and large leakage capacitances. The device uses the patented AMP Plus measurement principle, which allows it to accurately distinguish between actual insulation faults and system-inherent leakage capacitances. It features a high-resolution graphic display for real-time data visualization and an intuitive user interface for configuration and diagnostics.

Product Parameters

• System Voltage Range: Supports monitoring of systems up to $690 \text{ VAC}$ or $1000 \text{ VDC}$ directly, and higher voltages with coupling devices.

• Supply Voltage: Flexible power supply options, typically $24-240 \text{ VAC/VDC}$.

• Measurement Range: Capable of measuring insulation resistance from $1 \text{ k}\Omega$ up to $10 \text{ M}\Omega$.

• System Leakage Capacitance: Handles high system leakage capacitances up to $1000 \text{ \mu F}$.

• Communication Interfaces: Built-in Modbus TCP, BCOM (Bender Communication), and a web server for remote monitoring.

• Output Contacts: Equipped with two separate alarm relays (Form C) for signaling pre-alarms and main alarms.

• Environmental Resistance: The "S" version features enhanced resistance to mechanical stress, compliant with specific rail and industrial vibration standards.

• Inputs/Outputs: Includes digital inputs for functions like remote reset or activating the "standby" mode.

Product Advantages

One of the core advantages of the iso685-S is its Measurement Precision in Complex Systems. Many standard monitors struggle with the harmonic noise generated by variable speed drives, but the iso685-S filters this noise effectively. Its Integrated Web Server is a major benefit, allowing technicians to view the insulation history and system status from any laptop without needing specialized software.

The Predictive Maintenance capability is also a key differentiator; by tracking the resistance trend over time, the device can warn operators of a deteriorating insulation level before a total failure occurs. Additionally, the Modular Expansion options allow it to work seamlessly with insulation fault location systems (EDS), which can automatically pinpoint the exact branch of the electrical circuit where a fault has occurred.

Important Considerations and Precautions

When installing the iso685-S, it is vital to ensure that Only One Insulation Monitor is active in the same interconnected IT system; multiple monitors will interfere with each other’s measurement signals, leading to false readings. The device must be connected with Proper Fusing on the supply side to protect the internal electronics from short circuits.

During commissioning, the AMP Plus Measurement Profile must be correctly selected based on the system type (e.g., whether large converters are present) to ensure the fastest possible response time. Technicians should also be aware that a High-Pot or Megger Test on the system cables must only be performed when the ISOMETER is disconnected, as the high test voltages can destroy the sensitive measuring input of the device. Lastly, ensure the Grounding Connection (terminal PE and KE) is made with high-quality, low-impedance wiring to maintain measurement accuracy.

Product Applications

The Bender iso685-S is the preferred choice for critical infrastructure where power continuity is mandatory.

• Maritime and Offshore: Monitoring the ungrounded power grids on ships and oil platforms to prevent blackouts caused by single-pole earth faults.

• Renewable Energy: Surveillance of the DC and AC sections of large-scale solar PV plants and wind turbines.

• Railway Systems: Ensuring the reliability of signaling systems and rolling stock electrical systems where vibration resistance is required.

• Industrial Manufacturing: Protecting continuous processes in chemical, glass, or metal production where an unplanned shutdown would result in massive financial loss.

• Mining Operations: Providing safety and reliability for mobile machinery and underground power distribution networks.
