ATE Electronics

 products set:

- 

CS axial wirewound resistors

 (2W to 15W), thanks to row 

materials of very high quality and reliability, can replace with 

better permormances resistors in ceramic glaze.

- 

Aluminium housed RB series

 (10W to 250W) can supply in 

small dimensions high power with low operating temperature.

- 

CS and RB series

 can be supplied on request in 

special 

versions

 (fuse resistors, high pulse overload, non inductive...) 

and with custom leads (high insulation voltage terminals, faston, 

screw....)

- 

3SM

 (3W) for surface mount applications wich allow the 

replacament of traditional axial resistors with the same electrical 

characteristics of 3CS type

- 

Anti moisture devices DAT

 (100W & 150W)

- 

Symmetry resistors SR

 (10W & 13W) for voltage divider and 

discharge of electrolitical capacitors.

CS Series

FEATURES

Easy replacement of vitreous enamel resistors with no cost increase 

and no performance loss.

The whole assembly is coated with multi-layer silicone coating to give 

maximum wire protection form -55°C to +350°C.

Performance improvement is obtained by close tolerance, very low 

temperature coefficient and excellent stability in operation under severe 

environmental conditions.

High level reliability due to ceramic core chemically inert and centerless 

ground for uniformity, selected wire element and completely welded 

construction terminal to terminal.

FEATURES

One of the main causes for electrical troubles on electrical and 

electronic sets is due to the moisture which is formed on components 

during variation of the ambient temperature.

A simple and economic way to avoid these problems, consists on 

application of anti-condensation devices (Heaters) which maintain the 

temperature inside the enclosure some degrees higher than the ambient 

temperature in order to prevent moisture condensation.

The Heaters DAT100 and DAT150 have been developed for this 

specific use.

Their main features are :

- Surface temperature limited to 70°C allows assembling without problems.

- A thermoswitch permits maximum power at very low temperatures, then 

reduces the power dissipated till turn off the devices at +55°C.

- The DAT models are provided with simple clip mounting for 35mm DIN rail.

- Use of power wirewound resistors, under MIL-PRF-18546 G specs., 

increase reliability and suitable supply voltage.

3SM Series

FEATURES

Easy replacement of axial power wirewound resistors without 

performance loss.

Performance improvement is obtained by close tolerance, very low 

temperature coefficient and stability in operation under severe 

environmental conditions.

High level reliability due to ceramic core chemically inert and centerless 

ground, selected wire element and completely welded construction terminal 

to terminal.

The whole assembly is silicon coated and thermoplastic UL94-V0 

moulded to give maximum wire protection from -55°C to +220°C.
