GENERAL

The HQ 4819 shaver can be recharged in 1 hour by

means of a ‘Fly Back Self Oscillating Power supply’.

This electronic circuit enables the battery to be charged

at 100-240 V, 50/60 Hz.

It is possible to have a shave directly from the mains.

The green LED comes on when the shaver is

connected to the mains and will blink to indicate that

the battery is fully charged.

The electronic circuit incorporates the following

functions and controls:

- a 900 mA Quick Charge supply

- a 30 mA Trickle Charge supply

- a 1.25V Dynamic supply when shaving from the mains.

- an open cell protection (Vbat < 2.5V)

- an inrush and surge protection (R1).

- a temperature protection of the battery.

(if Tbat - Tamb > 5°C or if Tbat > 65°C, charging will

switch-over from quick charge to trickle charge).
