Electrical panel surge suppression device
HDU1-II20D series surge protector device(hereinafter referred to as SPD) is used for power supply system such as IT,TT,TN-C,TN-S,TN-CS, etc. for low-voltage AC distribution system, for indirect lightning and direct lightning or other A surge of transient overvoltage is protected. The SPD has a common mode(MC)protection and differential mode(MD) protection. The SPD complies with GB/T18802.1/IEC61643-II.
The main technical parameters:
Installed at the junction of LPZ1 or LPZ2 and LPZ3, 35mm standard rail is installed, and the multi-strand wire connecting enamel is 2.5-16mm2.
The SPD must be set to protect at each pole. Use a fuse or miniature circuit breaker or SOD backup protector.
Applicable to household distribution boxes, computer equipment, information equipment, informaiton equipment. Eletronic equipment and control equipment in front of or in the nearest outlet box.
Main structure and working principle:
SPD is a port, anti-stock protection, indoor fixed installation, voltage limited type.
SPD built-in disconnector. When the SPD fails due to overheating and breakdown, the disconnector can automatically detach its grid and given an indication signal. When the SPD is woking normally, the window product displays green, and when it fails, it displays red.
The SPD of 1P+N,2P+N,3P+N consists of SPD+NPE zero-ground protection modules of 1P, 2P, and 3P, and is applied to TT, TN-S and other power supply systems.
1.Response time is no later than 25ns
2.3 phase protection for TN-S,TT and other systems
3.It is easy for installation and maintenance by Pluggable module.
4.Protect low voltage users' equipment from indirect lightning discharge.
1.See the safety of seeing, statusindicator, in the case of a disconnection, the indicator turns red and the SPD needs to be replaced.
2.Quality Assurance: Don鈥檛 let the quality problems do damage to our brand
3.Has a high tech lab which I approved by CNAS(China National Accreditation Service for Conformity Assessment) All our test reports can get approved by TUV, KEMA,etc
Power,communications, construction, security, transportation, petroleum, military industry, factory automation, new energy, all kinds of power supply and signal equipment. Let鈥檚 see the power industry.
Power industry: With the rapid development of electronic technology, automatic control systems are increasingly used in all aspects of power production. While power workers benefit from the great convenience of microelectronic technology, they also suffer huge losses once they are damaged.
Lightning protection of power system, power plant system, substation, power system, wind power generation, solar photovoltaic power generation.
Q:Can you design according to our request as we want to sell our own kind?
A: Of course! We also have our own mode which is different from the common type on the market.
Q:Can you send a sample to test before order?
Q:Can you offer special discount?
A:For bulk order, discount is available.
Q:Do you have a lab?
A:Yes, Our lab have been assessed and found eligible to participate in UL witness data program, as well as testing at manufacturer鈥檚 premises laboratory approval by TUV Rheinland Group. Thus, we have the high level stand in SPD produce, technology according to IEC and UL standard.
Q:Do you have special person for after-sale service?
A:Yes, you can contact me directly if the product has any problem.
