2.9

Overtemperature Protection

Protection against overheating is provided by thermal cut-out TC1.  Should the temper-
ature of the main transformer (T1) rise to an unsafe level, TC1 will interrupt the supply
voltage to the control circuitry and the supply will shut down. There is some hysteresis
in TC1 and only after the temperature has dropped by approximately 5°C will it restore
power to the control circuitry, thus restoring normal operation.

2.10

Mains And/or Power Supply Fail Alarm

In the case of a mains and/or power supply failure, a "logic 0" (0V) is available at the
"Mains/PS Fail Alarm" output, even with a battery connected across the main DC out-
put.

If there is no fault with the mains or power supply, the main DC output voltage (typ.
+13.8V) is supplied to this alarm output via Q8 and R99.

2.11

Noise Modulator

2.11.1

Issue 05 & 07

Q11 and Q12 form the white noise circuit and are further amplified/buffered by Q13.
The noise modulates the frequency of oscillation of IC4, the switched mode control IC.
The purpose of the noise modulator is to spread the discrete harmonic frequencies
energy of the switching circuits over a wide bandwidth so that possible interference is
minimised.  This results in an overall reduction in noise of approximately 10dB.

2.11.2

Issue 03

A noise modulator PCB is available as an add-on for Issue 03 PCBs, under IPN 220-
01268-00.  This solders on to TP4 and works as described above.
