Delixi inverter analog output fault analysis

1. For pure resistive loads such as incandescent lamps, resistance wires, electric furnaces and other equipment, the power of the voltage regulator should be 1.5 times the power of the load equipment - 2 times that of the load equipment, for example, if your electric furnace is about 250W, you can choose a voltage regulator with a power of 500W. 2. Rationality ...

Application of air switches (circuit breakers). Delixi air switch, also known as circuit breaker. It is a switch that actively closes as soon as the current in the circuit exceeds the additional current. Air switch is a very important electrical appliance in the low-voltage distribution network and electric traction system.

1. Although the air switch is a type of circuit breaker, it is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. However, air switches are used in low-voltage distribution networks and electric traction systems, mostly on the low-voltage side. Widely used in the home, such as general household switches ...

1. There is no output, no voltage indication or no start when the machine is turned on. Overvoltage or undervoltage maintenance 1. Adjust the internal output voltage adjustable potentiometer 2. The wrong phase and the lack of phase are maintained, and the two phases are arbitrarily replaced by three phases 3. The main control circuit board is broken 3. Replace 4. The output AC has been ...

LDO, or low dropout regulator, is a low-dropout linear regulator that uses a transistor or field-effect transistor (FET) operating in its saturation region to subtract the excess voltage from the input voltage used to generate a conditioned output voltage. ...

It shows that the voltage regulator base is not voltage corrected, and the voltage regulator in this situation is like a transformer, the higher the input voltage, the higher the output voltage, the input decreases and the output voltage also decreases. This...

1. Nominal value A suitable approximation of a switchgear or component and equipment to mark or identify it. 2. Limiting value The maximum or minimum promise of a quantity in the specification and specification. 3、 ...

1. What is a switching regulator? Switching voltage regulators, some people call it regulators, voltage regulator sources. Complete voltage regulation, is the demand control system (negative feedback), from the automatic control theory we know that when the voltage rises, it will be lowered through negative feedback, and when the voltage drops, it will be ...

Press the undo function key first, then press and hold the school time function key, then adjust the time and date to the current moment, press the punctual function key again, adjust the time that needs to be closed and open to the specified value, if you need to set multiple groups, then press the punctual function key to set, without multiple groups ...

1. When the main circuit is equipped with a total leakage maintainer, the main barrier switch, the branch barrier switch, the main circuit breaker, the branch circuit breaker or the main fuse, and the shunt fuse should also be installed. When the total leakage maintainer is a leakage circuit breaker with short-circuit, overload, and leakage maintenance functions, it can not be ...

1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the operating current balance in the zero sequence current transformer and causes the leakage maintainer to malfunction. If you want to use the neutral line of the power branch line as the neutral line of the lighting branch line nearby, it will cause the leakage of the power branch line.

Delixi Electric launched a new "product intelligence" series of products, with outstanding quality and higher cost performance of professional competitiveness, to meet the green consumption demand for low-voltage electrical appliances in the field of construction and real estate, and promote China's low-voltage electrical profession into a new green development era. This "product wisdom" ...

Most modern LDOs and switching regulators operate reliably under no-load conditions, and some older power devices require a minimum load to ensure stability, because one of the electrodes that needs to be compensated is affected by the payload resistance. For example, the LM1117 requires a load current of at least 1.7 mA (most ...

The forward rotation control of the asynchronous motor, the peers of the double contactor and the button are doing more, but is there anyone who will use an AC contactor to achieve the forward rotation control effect of the motor? Practical application: general bench drill, letter ...

Circuit breakers account for a very large proportion of electrical sales and have a wide range of applications, but there are different standards for circuit breakers. For example, 1P, 1P+N, 2P, etc., there are also differences between them. 1. 1P circuit breaker, it is a single-stage ...

　　My name is Inverter, and among the many new energy-saving products, I am known as the "energy-saving forward" for my excellent function. In today's world, extreme disasters occur frequently, with melting glaciers, rising sea levels, persistent droughts, and heavy rainfall.

First of all, when the transformer is faulty, we must cut off the power supply of the transformer through abnormal methods for the first time, and many major electrical fires and electric shocks are caused by the main gate is not closed. Now let's take a look at what to do. ...

Delixi plastic case circuit breaker is also called equipment circuit breaker, the external contact of the grounding terminal, arc extinguisher, tripper and operating organization are installed in a plastic shell. Auxiliary contacts, undervoltage trippers, parallel trippers, etc. Most of them are modular, very compact in structure, and generally do not consider maintenance ...

1. According to the requirements of the device part and the needs of the maintenance function, reasonably select the motor maintainer model and its various maintenance action parameter settings; 2. According to the requirements of the product operation manual, the correct device should be connected correctly according to the use of each terminal, and the operating power supply should be connected to the control ...

1. What is a switching regulator? Switching regulator, English (regulatior), some people call it a regulator, a voltage regulator source. To achieve voltage regulation, it is the demand control system (negative feedback), from the automatic control theory, we know that when the voltage rises through negative feedback to reduce it, ...
