Product Overview
BENDER isolated power panel is a safe power supply solution designed for critical medical areas. The core goal is to achieve equipotential power supply through isolation transformers and precise monitoring technology, avoiding the risk of electric shock caused by grounding faults. The product is divided into three categories: standard type, dual output voltage type, and dual system type. It can expand sockets, grounding components, and fault location systems according to the needs of medical scenarios, and is equipped with communication gateways and remote indicators to form a "power supply monitoring positioning monitoring" full chain safety system. It strictly follows the electrical standards of the medical industry and is suitable for scenarios such as operating rooms and intensive care units that require extremely high reliability and safety of power supply.

Key issues
Question 1: What are the core differences among the three core models of BENDER isolated power panels (standard type, dual output voltage type, dual system type)? How to choose based on the scenario?
Answer: The core differences are concentrated in the power supply system architecture and voltage output capability. The selection logic is as follows: ① Standard type (IP series): single isolation system+single voltage output, power 3kVA~25kVA, suitable for most intensive care units, diagnosis and treatment rooms and other single voltage demand scenarios; ② Dual output voltage type (ID series): single 25kVA transformer+dual secondary winding, simultaneously outputting 120V and 208/240V, equipped with dual LIM2010 monitors, suitable for space limited scenarios that require power supply for both ordinary medical equipment (120V) and high-power equipment (208/240V); ③ Dual system type (IX series): Two independent isolation systems, each equipped with transformers and monitors, supporting seamless switching in case of faults, suitable for critical scenarios such as operating rooms that require extremely high power supply reliability.
Question 2: What is the core function of LIM2010 line isolation monitor? How to quickly locate grounding faults?
Answer: The core function of LIM2010 is: ① Real time monitoring of the insulation status of the isolated power supply system, supporting 2mA/5mA response value setting, with digital and analog display; ② Equipped with self checking and self calibration functions, it can monitor faults such as overvoltage, undervoltage, overload, and overheating and trigger sound and light alarms; ③ Support linkage with EDS461 series fault location module. Rapid positioning process for grounding faults: ① LIM2010 triggers an alarm after detecting a grounding fault; ② EDS461 module automatically activates and receives test pulses sent by LIM2010; ③ The current transformers distributed in each branch circuit capture pulse signals; ④ EDS461 analyzes signals through RS-485 interconnection and displays the fault circuit location on LCD/LED; ⑤ Remote indicator synchronous alarm, supporting up to 708 sub loop monitoring.
Question 3: What are the expansion capabilities of BENDER isolated power panels reflected in? How to achieve centralized management of communication monitoring system?
Answer: The expansion capability is mainly reflected in three aspects: ① Distribution expansion: Standard 8-way branch circuit breakers can be expanded to 16 ways, supporting Plug On/Bolt On two types, with current specifications covering 20A-60A; ② Function extension: Can add hospital level sockets, grounding sockets, PLC control modules (up to 12 device controls), EDS461 fault location system; ③ Monitoring Expansion: Supports MK series remote indicators and sound and light alarms, and connects to a communication gateway for centralized management. Centralized communication management method: ① Hardware level: Connect all devices through COM460IP (Ethernet/Modbus/TCP) or FTC470XMB (Modbus/RTU) gateway; ② Functional aspect: Real time viewing of device status and fault location on the web page, supporting email/SMS alarm push; ③ System integration: Compatible with OPC servers and SCADA/BMS building management systems, achieving unified monitoring of medical area power supply systems.
