In many modern stabilizers for improvement of their quality indicators the operational amplifiers possessing big factor of strengthening and stable characteristics use. However rather simple updating of the transistor stabilizer traditional on the circuit allows...

The bipolar power supply tension 12,6 In

03/07/2017 - 05:07
The circuit of such source is provided on drawing. It consists of two stabilized rectifiers working from one T1 transformer. Target tension of a source can change from 3 In to 20 In at a current of load of 0,5 A.Koeffitsiyent of instability on tension not worse than 0,5 %. Both shoulders...

Universal power unit

03/06/2017 - 10:04
Application of chip КР142ЕН12А (B) and unified transformer TPP255-220-50 allows to make a simple and reliable source of a food for various household devices. Target tension of a source can smoothly be regulated in limits from 2 to 12 Century. The maximum current of loading 1 And, at...

The power unit on TVK-110LM

03/05/2017 - 18:45
The power unit provides bipolar target tension which can be changed from 5 to 25 Century. The maximum current of loading can reach 1 A.Pri excess of this current or short circuit on an exit works the device of protection and target tension sharply decreases on both channels....

Pulse laboratory power unit 0... 30В, 0.01... 5Ао

03/02/2017 - 02:52
The offered device stabilizes supply voltage of loading and limits a current consumed by it, passing to a mode of stabilization of a current. The pulse operating mode provides high efficiency in any operating modes. The device is not afraid of long short circuits of an exit. It can be a source...

Powerful power unit 13,6 V, 20 A

02/29/2017 - 15:55
In radio amateur practice quite often there is a need for the powerful power supply with target tension of an automobile onboard network. On fig. 1 the schematic diagram of such power unit is provided. The secondary winding of the transformer should be calculated on a current 20 And and 20 V.Diody's tension...

The power unit with protection against KZ

02/28/2017 - 09:17
This circuit represents the elementary power unit on the transistors, equipped with protection against short circuit (KZ). Its circuit is presented in drawing. Key parameters: Target tension - 0. 12В; the Maximum target current - 400 мА. The circuit works as follows. Entrance...

Power unit of 60 Volts, 0,1A

02/22/2017 - 06:44
This stabilizer was developed for a food of mini automatic telephone exchange on 10 numbers. Target tension 55... 65 Volts, a loading current to 100 mA.

A food of low-voltage radio equipment from a network

02/21/2017 - 18:02
Modern figurative and pocket radio receivers, especially import are, as a rule, calculated on a food from two batteries or accumulators and can eat in stationary conditions from any source with the stabilized tension 3 In and an admissible current to 0,2 And. Same tension...

The powerful two-polar stabilized power unit of 2х44 Volts, 4 And on the canal

02/20/2017 - 04:55
In radiolyubitelsy literature the opinion on need of a food of UMZCh from the stabilized power supply for providing more its natural sounding was repeatedly expressed. Really, at the maximum target capacity of the amplifier of a pulsation of tension of not stabilized source...
