Power supply 3 pin

DC-DC Converter Tutorial Switching power supplies offer higher efficiency than traditional linear power supplies. New York engineer Reginald Neale recently sent pictures of his antique and unusual electronic collection. Designed to match your Surface Pro 3, the 36-watt power supply provides power when you need it, or lets you charge your battery when you're working near an outlet.
I need an auto-transfer switching control diagram for use in main-emergency power supply system.
You can refer to Changeover device to DIN VDE 0108 – Power systems and safety power supply in buildings. Phase monitor K1 is energized via the main supply and immediately energizes contactor relay K2. I Have Gen-set and would like make a ATS between Main line and generator, so I would like to send me a simple Diagram and colored pictures for each item and how connected them by diagram wires.


Connecting the main and auxiliary in parallel is not allowed but to connect the N and PE in parallel is allowed? Another idea would be to use 4-pole contactors (to disconnect also the neutral) but unfortunately our approved supplier have only 3-pole contactors. On the other hand some standards such as Canadian Electrical Code does not require, nor is it general practice to provide additional ground fault protection where the essential loads are energized from a separately derived power system, such as an engine-driven generator set.
This is a trade-off in possible electrical equipment damage, in order to keep the essential circuits in operation, as decided by an operator. I Have Dessile generator and would like make a ATS between Main line and generator, so I would like to send me a simple Diagram and colored pictures for each item and how connected them by diagram wires. I used a similar circuit in a cubicle design and I have been asked for my colleagues to remove one relay that performs the crossed interlock between the contactors.
It is considered for safe interlock against any contactors manual operation via dip switch that provided for alternative operation on magnetic relays.


PLEASE HOW CAN I USE A 3POLE RELAY THAT HAS L1, L2 AND L3, WITH T1, T2 AND T3 AS A CHANGEOVER SWITCH FOR A SINGLE PHASE POWER INPUT FROM GRID AND A SINGLE PHASE POWER INPUT FROM GENERATOR?

So I figured it would be a great idea to feature one of his interesting gizmos for our #ThrowbackThursday blog.Here is Reginalda€™s Heathkit PS-3 500-Volt power supply.
However according to some recommendation no ground fault protection is applied to any emergency system where the capacity of a generator is 500 kW or less.
