Delta Pulse

[kt315]

i need help in delta pulse
the mosfet heat quickly i used heat sink and i used 840 but again heat i used the old cicuit here in the picture i didnt add this diode and capictor around mosfet what i can do ?
my coil in 440 uh and 3 ohm uesd damping resistor 680 ohm
what i can do???????????????????????????????????????????????? ????????????????? please help me and if any body here make delta pulse i need his e-mail .....

DP is working good without the HV diode and the capacitor. Check PULSE WIDTH, check all connections to the coil - from MOS-FET to connector, connector itself. if you use TURKISH PCB layout check ALL WIRES POIN-TO-POINT OUTER CONNECTIONS.

What are the specifications of coil ?

Please can anyone tell me the voltage value of "E" ?
for me the value is 5.4 V it is right or wrong ?

why metal and no plastic potentiometers. ?

give pls dimensions sizes those you mean.

i have problem with v meter. the voltage where count is 005,0 mv normal and 1oo,5 mv when approach metal in antenna. help

Hi kt315
The best choice is S16KN1 it can be used as much as possible because the depth of the Legs =0.4mm Possible to place a 0,125W resistors under the pots. and u get 0.1mm if cut the smalle metal up the leg.

hi kt 315 how to possible iron reject mod in delta pluse / xr 71 can you explain some detail next revise

seems you are off the matter. you can reject small trash like a cola can, nails etc. I suggest you to read a manual on Deepers, in another thread. that is nice good description what the deeper does and designed for.

Thanks KT315
Potentiometers attached similar picture we use here in Argentina.
regards

attached files that i googled. can i place a resistors under the pots, for example? is there a necessary height or gap or space for 0,125W resistors?

hello Jose,
7909 is a option. you can use either the diodes or 7909. automatic-manual is also will be a option, there will be a connector at PCB for the switch.

I need an info on potentiometers which are more popular among people - dimensions sizes.

regards.

Hello KT315
I think VD8 and VD9, must be removed to function properly the controller 7909.
As the scheme of manual, automatic?
This is what I use.
