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
Maintains minimum operating temperatures in enclosures
Helps to prevent failure of electronic components caused by condensation and corrosion
Heating power adjusts to ambient temperature
DIN rail mountable
