Product Detail:

1.Application

lectrical & Electronic enclosures

Telecommunications systems

Display panels

Automatic teller machines(ATM'S)

Access & Parking control systems

Ticket dispensers 

2.Determining the required heater size

PH=(A x ΔT x K)-PV 

PH=Required heating power for your application in Watts(W)

PV=Heating power generated by existing components(e.g.a

transformer)in Watts(W)

A=Exposed enclosure surface area in square meters(m2)

ΔT=Temperature differential between the desired minimum interior temperature and the Lowest possible external temperature of the enclosure in Kelvin(K), 1.8˚F=1˚C=1K K= Heat transmission coefficient of the enclosure material.

used:

Painted steel:5.5W/m2K

Stainless steel:3.7W/m2K

Aluminum:1.2W/m2K

Polyester/Plastc:3.5W/m2K

For outdoor appllcations it is recommended to double the heating power.
