When choosing a relay with QC lead-out method, please do not use soldering to connect the load lead-out end of the relay. If other welding methods are used, it is also necessary to ensure that the heat generated by welding will not affect the function of the magnetic latching relay

Please apply a suitable voltage to the coil according to the coil polarity specified in the manual, otherwise the operating voltage of the relay will increase or even not operate; it needs to be changed When driving the polarity, please use the "-R" type relay.

The factory state of the Magnetic Latching Relay is in the state of action or return, but it may change due to the impact of transportation or relay installation and other factors, so please set it to the state of return or action as required when using it (when the power is connected);

Oswell E-Group Ltd. recently held a team culture building activities. When we came to the countryside, we not only held team projects, but also carried out some water projects. All of us had a great time, not only relaxed physically and mentally, but also promoted the communication between colleagues outside work and enhanced the team cohesion.

Artificial intelligence is set to be crucial to managing the significant increase in battery energy storage to support the grid towards net zero, a new paper states.

The 7550A is an ammeter with a measurement range from 1µA to 250A. The voltage on the shunt is switched to the internal four-and-a-half-digit AC and DC ammeter directly displayed by the five file-bit buttons and on the external output terminal. AC and DC current values with high accuracy and resolution.

When we open the power distribution cabinet, we can see that there are many current transformers in it. Some power distribution cabinets have only one, and some even have five or six. In fact, they all induce current signals from the bus, but the measured currents have different effects. So what role do they all play in the power distribution cabinet?

Simply put, it is to effectively use the range of the voltmeter. For example, a voltmeter with a full scale of 75mv, the object to be measured is a current of about 20A, you choose the shunt resistance R, and R*20A should preferably fall on the middle of the 75mV range, such as 3mΩ to 3.5mΩ for comparison Suitable.

In many work links, such as quotation, after-sales, logistics, etc., during the epidemic, we did not completely press the pause button, but all departments worked together and cooperated to promote the promotion and development of business and various tasks.
