Basic modules: Each model includes CPU module, power module, binary I/O module, analog input module, LHMI module, communication module, backplane module, etc. The module types and parameters of different models may vary slightly. For example, RED615 uses PSM0004 power module, REF615 uses PSM0003 power module, etc. In addition, type testing was conducted on the IEC LHMI module DIS0012, and since the PCBA of ANSI and IEC LHMI are the same, the test results are also applicable to the ANSI LHMI module DIS0014.

Various test results

Mechanical structure inspection: Marking and mechanical structure comply with IEC 60255-1 and IEC 60255-27 standards; The embedded shell level is IP 54 on the front and IP 10 on the back and connection terminals, in compliance with IEC 60529 standard; The electrical clearance and creepage distance comply with IEC 60255-5 and IEC 60255-27 standards, and the results are both OK.

Overload and input testing: Under rated current, rated voltage and other parameters, the thermal tolerance, dynamic current tolerance, input impedance, load, voltage tolerance, etc. all meet the requirements of IEC 60255-1 and IEC 60255-27 standards. For example, for a rated current of 0.2/1A, the continuous thermal tolerance is 4A, and the 1-second thermal tolerance is 100A.

Power module testing: In terms of auxiliary voltage, PS-H has no effect at 38... 300 VDC, 38... 264 VAC, and PS_L has no effect at 12... 72 VDC; In the voltage drop immunity test, the product can operate normally or restart under different voltage and residual voltage conditions; During the auxiliary power supply voltage interruption test, the product was able to shut down and restart normally; The tests for DC auxiliary voltage ripple, gradual shutdown and startup, and DC power polarity reversal all meet the requirements; At the same time, the power consumption of different power modules is provided.

Contact testing: Different types of contacts (bipolar power output, unipolar power output, signal output, etc.) meet the requirements of IEC 60255-1 and IEEE C37.90-2005 standards in terms of making ability, breaking ability, mechanical tolerance, etc. For example, the bipolar power output continuously carries a current of 8A, and the 3-second turn-on and carrying current are 15A, etc.

Electromagnetic compatibility testing: Pulse interference testing at 1MHz/100kHz, pulse interference testing at 3MHz and other frequencies, electrostatic discharge testing, radio frequency interference testing, surge immunity testing, power frequency magnetic field immunity testing, and other electromagnetic compatibility tests all comply with the requirements of corresponding standards (such as IEC 61000-4 series, IEC 60255-26, etc.).

Insulation testing: dielectric testing, impulse voltage testing, insulation resistance measurement, protective grounding resistance testing, etc., in accordance with the requirements of standards such as IEC 60255-27 and IEEE C37.90-2005. For example, passing the dielectric test under the conditions of 2kV, 50Hz, and 1 minute.

Mechanical testing: vibration testing, impact and collision testing, earthquake testing, mechanical durability testing, etc., in accordance with the Level 2 requirements of standards such as IEC 60068-2 series, IEC 60255-21 series, IEEE C37.90-2005, etc.

Environmental testing: dry heat testing, dry cold testing, wet heat testing, temperature change testing, storage testing, etc., in accordance with the requirements of IEC 60068-2 series, IEEE C37.90-2005 and other standards. For example, the dry heat test passed at+55 º C for 96 hours and+85 º C for 16 hours (some products passed at+70 º C).

Characteristic

Compact and flexible design: adopting a withdrawable unit design, the structure is compact, occupies small space, and is easy to install, test, and maintain. Products such as REF615 and RET615 have a pull-out design that facilitates replacement or maintenance during equipment operation, and are compact in size, making them suitable for space limited substations and other locations. This design can also reduce the space required for equipment installation, improve space utilization, and reduce equipment costs.

Comprehensive functionality: covering multiple protection and control functions, capable of meeting the needs of different power systems. For feeder protection, it has functions such as underground and overhead cable fault detection (CFD), high impedance (HIZ) fault detection, arc flash detection (AFD), etc. REF615 can effectively detect and respond to various faults during feeder operation. In terms of transformer protection, sensitive differential protection is used for inter turn faults, overexcitation (V/HZ) protection, etc. RET615 can provide comprehensive protection for transformers. In addition, it also includes various protection functions such as overcurrent, thermal overload, grounding fault, overvoltage, undervoltage, as well as special functions such as frequency protection and phase discontinuity protection, comprehensively ensuring the stable operation of the power system.

Good communication compatibility: Supports multiple communication protocols, including IEC 61850 (supporting Edition 2 and Edition 1, including HSR, PRP, GOOSE messaging, and IEC 61850-9-2 LE), IEEE 1588 V2 (for high-precision time synchronization) Modbus ®、 DNP3, etc. Through these protocols, the product can communicate and interoperability with devices from different manufacturers, facilitating the construction of complex power automation systems, achieving data sharing and remote monitoring, and enhancing the level of system intelligence.

High reliability: Through careful design and selection of high-quality components, the product has strong reliability and can provide stable and high-quality electricity, reducing equipment failures and power outages. For example, in some industrial sites with extremely high requirements for power reliability, such as steel plants, data centers, etc., the 615 series products can operate continuously and stably, ensuring normal production and business operations, and reducing losses caused by power problems.

Easy to upgrade and maintain: With ready-made standard configurations, it is convenient to quickly set up and customize, supports flexible system upgrades, and does not require rewiring or component replacement. When expanding or upgrading the system, users can achieve it through software configuration or adding modules, reducing upgrade costs and complexity, and improving system adaptability. In addition, it also provides a wide range of lifecycle services, such as training, customer support, maintenance, and modernization, to provide users with comprehensive protection.
