2 CIRCUIT DESCRIPTION RT2047 DSC - PART II
In case of a short-circuit over the output R5 and D3 limits the current through IC1 and T4 to approx. 250
mA and R1 - R3 and D3 limits the current through T1 and T2 to approx. 15 Amp. The temperature of the
cooling surface will increase and activate the thermal protection circuit inside IC1 and lower the output
voltage, even though a short-circuit of the output should be avoided.
The diode D1 protects against reverse input voltage. A fuse will blow in case of reverse input.
