Product Description:

1. Product Description:

The WYJ series D.C. Regulated power supply is the one whose output voltage is variable. They have the functions of continuous adjustment output voltage and fixed output to be chosen as per requirements. The circuit consists of integrated circuit and power amplifier, with single-way output and multi-ways independent output. The circuit has functions of high steady in capability, reliability in characteristic, steady in output voltage, small size novel appearance, suitable for scientific research institutes, manufactories, electric appliance serices and so on.

2. Product Characteristic:

Two-way output
Two numeral tubs show the value of output voltage and current separately through the choice switch.
The regulated voltage and current can be switched automatically and showed by luminous tube.
The two-way output voltage can be serial-shunt operation as per requirement, while in serial and shunt operation ,one of the main
power can follow the voltage or current(shunt).
It adopts the mode of protection of current limitation, which can be adjusted as per requirement.
It can add up to 5V/3A fixed voltage output as the users’ requirements.
Full plastic frame, novel appearance.



Power reaction:CV≤1x10-4+0.5mV CC≤2x10-3+1mA

Load reaction:CV≤1x10-4+2mV CC≤2x10-3+3mA

Measurement and weight:290x158x135mm 3~6kgs
Output voltage: Between OV-30V can be adjusted continuously
Output current:0-30A(WYJ1730SC 30A/WYJ1730SL 30A
WYJ1730SC 30A/WYJ1730SL 30A)

Q:A 8000kva transformer can bring the maximum load
A good transformer can work at full capacity. But affect the service life. It is best to 80% of the power of this transformer is the best.
Q:Is the LTC transformer a regulated voltage transformer?
If equipped with a load regulator is called on-load tap-changer If equipped with no load regulator is called no-load voltage regulator
Q:Transformer turns around the number and how much V is calculated
Transformer turns around the number and how many V calculation method: 1. Find the number of turns per volt: Number of turns per revolution = 55 / core cross section For example, the core section = 3.5 ╳ 1.6 = 5.6 square centimeters Therefore, the number of turns per revolution = 55 / 5.6 = 9.8 turns
Q:What are the transformer capacity?
Transformer capacity has the following (unit kVA): 10 20 30 50 80 100 125 160 200 250 315 500 630 800 1000 1250 1600 2500 and so on
Q:Transformers are divided into several. What is the role of each? To be specific!
(Ii) Classification by purpose Transformers according to their use can be divided into power transformers, audio transformers, pulse transformers, constant voltage transformers, coupling transformers, autotransformers, isolation transformers and other. (C) according to the core (or core) shape classification Transformers according to the core (core) shape can be divided into "E" type transformers, "C" type transformers and ring transformers.
Q:What is the reason why the dry transformer is loud
500kva below the dry-type transformer noise 56 to 58 dB or so, 630kva above 62 to 65 dB or so! This is our factory data. The dry-type transformer sound is great. Big like cattle called the same, because the core is loose!
Q:The specific steps and procedures for installing the transformer
Oil-immersed or dry-type transformers are generally installed by the engineering team or factory installed do not know how much capacity your transformer is electronic or industrial power system
Q:Production of high and low voltage switchgear transformer industry belongs to what industry category
Production of high and low voltage off cabinet transformer enterprises are mechanical and electrical manufacturing industry
Q:50KVA transformer maximum load is how much?
50KVA transformer can bring the maximum load is, 1.45 * 50 = 72.5A or so
Q:Why is the transformer coil insulation?
It is easy to understand because the transformer is used in different environments, according to different insulation level selection, can extend the life of the transformer
