Can the battery valve be connected directly to the power supply

When you follow the wiring diagrams, the alternator is directly connected to the battery (if that connection fails the the alternator can be damaged) and the battery is connected to the vehicle electrical system. The common point is usually the battery positive terminal or the other end of the battery positive cable.

B136 power supply for valve battery radios

90v HT supply of between 10 and 20mA: 2) 1.5v LT supply of between 100mA (4-valves or 25mA) and 250mA (5 valves of 50mA). However, being battery powered, the LT supply would on average be less than 1.5v and it is particularly important not to over-drive battery valves, a figure of 1.4v seems more appropriate.

Applications of Metal Oxide Varistors (MOV) in Power Supply

The monomer flow current of metal oxide varistors (MOV) can be 70kA (8/20μs) and the varistor voltage can reach 1800V with a nanosecond grade response speed. So MOV is widely used in the lightning protection of AC power lines and low frequency signal lines. Since MOV is mainly used for the surge protection of power supply interfaces, it has a wide

Power Supply for Battery Valve Radios

A number of visitors to this site have asked about power supplies for operating battery valve radios from the mains. Many later radios use four 7-pin valves and require a 90V HT supply at typically 12mA and a 1.5V LT supply at 125mA or 250mA depending on the valves used. The original batteries are sadly no longer made.

grounding

Never ever connect your radio or amp directly to the vehicle battery. You always ground to body of the vehicle. Positive can go to battery but best to follow manufacturer on location. If your new radio comes with a fuse on the ground, cut it off so as to only fuse the positive lead.

Can I connect my laptop that runs on 18.5 V directly to a 12 V battery or 24 V (2 batteries)? That''s 18.5 V on the laptop''s DC plug. Laptops have voltage regulator circuits on the mainboard so they can accept slight differences in input voltage, but supplying 6.5 V less or 5.5 V more to a 18.5 V DC plug is very probably too much of a difference.

Run laptop off AC power without charging battery

To test whether this can be done safely, turn off the computer, remove the battery with the AC adapter plugged in, and try turning it on. If it turns on, you should be OK. Some laptops may not be as well-behaved when you do this, with reduced performance when the battery is removed especially if the AC adapter can''t supply enough power for full ...

Why is the ground pin always connected to the "negative" power supply?

As you can see with an isolated power supply you can connect ground to either positive or negative or neither. Also conveniently, there''s never a "negative power supply" pin. ... you''d easily see the differences between e.g. measuring the voltage directly across the battery and directly across the load resistor!

$begingroup$ @Noldorin It was the asker''s "idealizing away" the wires of a motor that caused them to believe that a motor should draw infinite current. To me, this answer takes things in the best possible order: first, it explains why the current isn''t infinite, as the asker thinks it should be; then, it explains why the current is even less than what it would be if that …

How to Wire a Car Stereo to a 12v Battery

The battery is not charged. To tell if the battery is charged you can use a multimeter, alternatively, you can tell by the strength of the headlights. You have connected up the wires incorrectly – See the correct way to connect your battery terminals. The radio doesn''t work – This could be because of a large number of factors.

Does it matter if a fuse is connected to the negative or positive ...

As the power supply has no ground / earth / chassis connection there is no danger of a single fault causing an alternate return path. ... in most low-voltage applicatons the battery is not directly connected to the conductive parts such as casing or heat sinks, and therefore it doesn''t matter where you put the fuse. ... rather than the negative ...

Should I connect my inverter to the battery or to the charge …

If the controller is connected to the battery or any other wiring terminals on the battery line, pv power will flow to everything connected, lights, inverter, all of it. Its like airing all the tires on your car from one point (controller) if there were a tube connecting all the valve stems (wiring), they will be at the same pressure, even if ...

Uninterruptible power supply

A large data-center-scale UPS being installed by electricians. An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.

A few important things about charging the Deck (voltages ...

Battery output is "open" and delivering 25W to the Decks components, thus effectively charging at 10W but it still delivers power to the Deck the entire time. Battery input is "open" but Battery output is "closed" since the input is higher than what the deck needs, the battery controller uses 25W to directly power the Deck and only uses the ...

[SOLVED] Directly powering a PC with a 12v battery. Skipping the PSU

Another approach would be to use four separate DC-DC converters to accommodate all of the usual supply rails. The main problem would be finding a 40-50A 12V buck-boost converter that can accommodate the 9-16V range of a car''s 12V electrical system.

Valve Amps: Power-supply

Modern valve amp power supply. The perfect valve amp power supply should be close to 100% stable with little variation to the B+ supply when the amp is driven to full power. A stable B+ supply was not possible with valve rectifiers and small Electro''s. A silicon Diode has only a 0.7V drop across it, which is negligible compared to the B+ 560V.
