Our advantages

Zhejiang Risesun Science and Technology Co., Ltd.(Abbreviated as Risesun.The former: Wenzhou City Risesun Electrical Meter Co., Ltd., established on Nov. 26, 1997.) is a national level high and new technology enterprise with the business range of research and development, production, sale and after-sales service for energy measuring meters and acquisition systems of consumed energy information. Its main products cover smart energy meter, IC card prepaid energy meter, din rail energy meter, STS keypad prepaid energy meter, multifunction energy meter, acquisition terminal of special transformer, data acquisition system, charging pile of electric auto, metering box and etc.

Risesun not only owns the international and domestic advanced production equipment, such as Model KE-2050, KE-2060, KE-2070 and FX-3L SMT machine imported from Japan, Model GKG-G2, Win-8 and DSP-1008 Printing machine, Model NS1000 reflow soldering machine and Model MPS-400B selective wave soldering machine, etc., but also has the international and domestic first-class high-grade, precision and advanced testing facilities, such as Model Tra2000 EMC immunity test instrument imported from Switzerland, alternating humid and hot and high and low temperature box, etc. Risesun is with the fluent product manufacturing process, the reasonable artwork layout and the scientific production organization, and is one of the earliest enterprises in meter industry forming Three-in-one Management System of ISO9001:2008, ISO14001: 2004 and OHSAS18001: 2007. Risesun sets up a R&D center both at Wenzhou headquarters and Shenzhen branch with a manufacturing base in Wenzhou. With geographical advantage of Shenzhen, Risesun has brought together senior experts in related fields and let them devote to providing advanced solutions to customers. Moreover, a variety of leading products have passed quality certifications of the international authoritative organizations like the Holland KEMA, the European Union CE-MID, South Africa STS, Switzerland DLMS and etc. Risesun pays attention to technological innovation, and has already built solid product quality security system by means of scientific management.

Today's Risesun, just as a round of Oriental Sun, is rising and creating greater glories with the help of the national macroscopic policy good solution and its research and development potential.

Q&A

Q: What kind of requirements do smart energy meter have to load switch?

A: The load switch of smart energy meter can be divided into internal or external mode. When it adopts the internal load switch, the maximum current of energy meter should not be more than 60A.

When it adopts the internal load switch, switch operation shall have Acr suppression measures (hardware or software), and its export loop shall have safety measures for anti false action and being easy to field test. Under the condition of above current, the lifetime of switch shall not be less than 6000 times. Imposing reference voltage on voltage circuit of energy meter, and under the condition of passing 1.2Imax to current circuit, carries out switch on and off test for 10 times; After the test, the energy meter shall work normally; when imposing 70% to 120% reference voltage on voltage circuit of energy meter, the load switch shall work normally.

When it adopts external load switch, energy meter shall output a set of switch signals, and the capacity of switch node is AC 250V, 2A. During normal operation, the outgoing switch signals shall maintain load switch closing and allow users to use electricity. When the control conditions are satisfied, the outgoing switch signals shall drive external load switch action and interrupt power supply.
