Pioneer VSX-33TX – Dead Standby Transformer

Unfortunately, with the 20+ year old receiver, the standby transformer (Pioneer part no ATT7043) is no longer readily available (on the internet anyway – next I''ll try some of the brick-and-mortar service places). So, I found a salvaged primary power board on ebay from a different model with the same standby transformer. I removed it

Onkyo TX-DS797 Standby Transformer substitution help

I have an Onkyo TX-DS797 av amp that I am trying to repair. We had a 600v power surge thanks to local power company that took out the units standby power supply. Unit was not on so I think the main transformer and guts is ok but the standby power supply is always on to feed the microprocessor and work the relay to enable the main power supply.

Transformer Standby Losses | Information by Electrical

If the transformer is reasonably new, then loss data should be available from the supplier. In the case of an old unit, the only reliable way to determine losses is by measurement, either use a true watt meter, or a utility type KWH meter for a known time.

Standby power

Standby power, also called vampire power [1], vampire draw, phantom load, ghost load, or leaking electricity, refers to how electronic and electrical appliances consume electric power.At the same time, they are switched off (but are

Transformer that doesn''t take power when not used

it eats 7 VA constantly all day even if the bells are not ringing. Not all of this is loss. In fact most of it is not loss. It is what is called "reactive power". The transformer temporarily "borrows" some energy from the mains, and then later in a cycle, returns most of that energy.

switch mode power supply

The flyback transformer is a misnomer and ought to be considered as a switched inductor with coupling, as it does store energy unlike an ideal transformer. However the addition of a small air gap allows more current with greater H fields now occupied in the air gap Not all the energy is in the gap but optimally it can be 2x as much as in the core.

Power Supply Energy Efficiency: Challenges and Opportunities

• If not, sleep and standby modes may dominate • Most power supplies always draw less than full rated power (part load efficiency) • Ideally, a power supply-containing product has minimal standby consumption, high operating efficiency across a wide range of load conditions, and is smart enough to "sleep" after inactivity.

equipments. From the standpoint of individual consumers, the energy utilization for standby power may not be substantial. But as a whole, the standby state power usage is a sizeable loss of electrical energy for the nation. While standby power does not perform the core functions of the equipments concerned, it is not always wasted power.

transformer

A transformer* transmits power instantaneously between primary and secondary; any energy storage is only incidental, a non-ideal aspect. *In the meaning of a transformer as an ideal one, i.e. small enough leakage inductance to ignore (or at worst, model as a series inductance), and large enough magnetizing inductance to ignore (I mag a small

How much power does an unloaded transformer consume?

It has about 300 v dc across the primary, but only generates charge in the flyback mode ( 8 amps dc ). It''s really light and small as all SM supplies are. It does draw more current than normal even if the load is not coupled because in a flyback supply you need to store energy in the core to be released into the load.

6 FAQs about [The standby transformer does not store energy]

Do Transformers consume power when plugged into a wall?

You get the idea. A typical home probably has five to 10 of these little transformers plugged into the wall at any given time. It turns out that these transformers consume power whenever they are plugged into the wall, whether they are connected to a device or not. They also waste power when powering a device.

Does a transformer match a load?

Matching a transformer to its anticipated load is a critical aspect of reducing energy consumption. In 2002, NEMA issued a Standard TP-1 in support of the U.S. Dept. of Energy’s guidelines for more energy efficient electrical devices.

How many Watts Does a transformer lose at no load?

That probably means a 100 or more watts. If the primary resistive impedance of the transformer was 1%, then the approximate resistive loss at no load would be about 18 W. Double this for total no load loss and it is about 40 W. You really need to find manufacturer data on the transformer.

How can a 150-c rise transformer reduce energy consumption?

In the engineer’s quest to reduce energy consumption, matching the transformer to its anticipated load is critical in achieving that goal. By applying a 150-C rise transformer to a lightly loaded linear circuit, the losses noted in TP-1 will be very close to the actual losses.

How do I know if a transformer has a loss?

Check the specification for your particular transformer. . If the transformer is reasonably new, then loss data should be available from the supplier. In the case of an old unit, the only reliable way to determine losses is by measurement, either use a true watt meter, or a utility type KWH meter for a known time.

Does a larger transformer have a lower PF?

A larger transformer should have a lower PF. Also the core material, and transformer design will have a considerable influence. Excitation voltage vs design voltage is a major factor. If we assume 3% loss at 35% load and that 50% of the loss at 35% load is no load loss, then for your 25 kVA unit we get 0.03 * 0.35 * 0.5 * 25,000 = 131 W.
