Installation Precautions high pressure hose fittings

Installation Precautions high pressure hose three phase online ups
(1) hose in a mobile or stationary, and can not bend over, it can not be bent at the root, at least to start bending at 1.5 times its diameter;
(2) hose moved to the extreme position not pull it too tight, should be more relaxed;
(3) try to avoid the hose twisting deformation;
(4) hose as far as possible away from the heat radiating member, fashion necessary insulation boards;
(5) Avoid hose external damage, such as the use of the same long-term friction surface of the member;
(6) If the hose caused by excessive weight deformation, should support members.

 

The inverter is a DC to AC transformer, which in fact is the process of transforming a voltage inverter.

The three phase online ups is a DC to AC transformer, which in fact is the process of transforming a voltage inverter.
Converter is the grid AC voltage is converted to stable 12V DC output, and the output of the inverter is Adapter 12V DC voltage into a high voltage alternating current of high frequency; likewise two portions are used with more than a pulse width modulation (PWM) technique. At its core is an integrated PWM controller, Adapter using UC3842, the inverter is used TL5001 chips. TL5001 operating voltage range of 3.6 ~ 40V, has an internal error amplifier, a regulator, oscillator, with dead-controlled PWM generator, low-voltage protection circuit and short circuit protection circuits.
Input Interface parts: input part has three signals, 12V DC input VIN, work ENB enable voltage and current control signals Panel DIM. VIN provided by the Adapter, ENB voltage provided by the MCU on the motherboard, its value is 0 or 3V, when ENB = 0, the inverter does not work, and ENB = 3V, the inverter is in normal working condition; and DIM voltage provided by the motherboard, which ranges between 0 ~ 5V, the different values of feedback to the PWM controller DIM feedback terminal of the inverter to the load current will be different, the smaller the value of DIM, the inverter output current greater.
