I / How to calculate the total power of the transformer?
1- Example a transformer with these characteristics:
- Primary 230V
2x 30V AC 2A
1x 9V AC 3A
Features 4 windings (1 primary and 3 secondary) and makes a total of 2x (30x2) + 1x (9x3) = 147VA (150VA)
According to the grid its price is 48.40 € TTC
2- Example a transformer with these characteristics:
- Primary 230V
300-0-300 VAC 0.2A
1x 9 VAC 3A
+ electrostatic screen
Features 4 windings (1 primary and 3 secondary) and makes a total of 2x (300x0.2) + 1x (9x3) = 147VA (150VA)
2 secondary windings are greater than 100V, so 2x 10% increase
The optional electrostatic display also adds 10%
According to the grid its price is 48.40 * 1.1 * 1.1 * 1.1 = 64.42 € TTC
II / How to order?
The basic price of this product is 1.00 € you have to order the quantity corresponding to the total amount in euros.
For the example above you would enter "64" in field quantity of your basket.
At the moment of validation of the command you will be able to inform us the characteristics of your transformer in the field Comments:
Here is a matrix to give us your information:
CAUTION IF YOU DO NOT SPECIFY THE VALUES OF THE DESIRED PRODUCT AS INDICATED IF THE ORDER WILL NOT BE TAKEN INTO ACCOUNT
Total power: 147VA
300-0-300V 0.2A (120VA)
1x9V 3A (27VA)
(+ electrostatic screen)
300-0-300 VAC means 2 windings with midpoint
2x300 VAC means 2 separate windings
The voltage to be indicated is the effective voltage, ie the voltage under load.
If empty the measurable voltage will be slightly higher (refer to column dU in%)
