Product Detail:

1.Applications

Electrical & Electronic enclosures

Telecommunications systems

Display panels Personnel booths

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)

¦¤T=Temperature differential between the desired minimum interior temperature and the Lowest possible external temperature of the enclosure in Kelvin(K), 1.8oF=1oC=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.

Specifications are subject to change without notice. Suitability of this product for its intended use and any associated risks must be determined by the end custome/buyer in its final application.

Compact heater in PTC technology
