Kerbl Transformer for Trough Heating

Kerbl Transformer for heated drinking bowl
• Switch the voltage from 230 V to 24 V
• Useable for all heated drinking tanks
• Protected against short circuit and overload by means of an easily replaceable auto fuse in the output output circuit
• Protected against overheating by integrated temperature limiter, automatically switches on again after cooling
• IP 65 (transformer) / IP 20 (connection)
• Available in 100, 200, 300 or 400 watts.
Which transformer should you choose?
If you want to heat a drinking boiler with a thermal power (P) of 80 watts, then a transformer for 100 watts (article number 8100112) will suffice. If you want to connect a 24 V heating cable, simply add the electrical power (= the number of W) of the cable. Consider the power loss through the power lines (see calculation example). This gives you the required minimum power for the transformer. Do not select the power of the transformer too accurately, so you can reserve for any extensions.
Calculation example:
5 x heated water tank with power consumption 100 watts = 500 watts
4 x frost protection heating cable 24 V with 30 watts = 120 watts
1 x frost protection heating cable 24 V with 15 watts = 15 watts
Total power consumption: 635 Watt
Provision for loss of conduct 15%
6.35 x 1.15 = 730 watts.
Rounded upwards in connection with reserve = 800 watts.
There are therefore two 400 Watt transformers required.
