GENERAL DESCRIPTION

GYSFLASH 30-12 HF and 30-24 HF provide a high powered stabilised power supply incorporating
SMPS (Switch Mode Power Supply) technology.
Designed to sustain 12V or 24V batteries (liquid/AGM/gel) for vehicles during diagnostic work, and will
ensure an ideal charging cycle for battery maintenance for the most modern vehicles and battery
types. These chargers can be fitted with cables up to 2x5m in 16mm². Changing battery cables
requires recalibration (cf. page 6).
These devices have 5 modes :
- Charge Mode: to charge liquid or gel electrolyte (lead, lead Calcium, lead Calcium-silver,
AGM...) starter batteries from 10 Ah to 400 Ah in 12V and from 10Ah to 200Ah in 24V (only for
GYSFLASH 30-24HF).
- Diag Mode and Diag + Mode: on a stationary vehicle GYSFLASH 30-12 HF and 30-24HF
supply up to 30A to ensure compensation of the current used by high-energy consumers (engine
fan, window regulator, electronic suspension, etc). Diag+ Mode enables the user to set the
desired regulated voltage level in the range 12V to 14.8V.
Change battery Mode: ensures a stabilised power supply to the vehicle during battery
-
replacement to preserve memory settings.
- « Showroom » Mode: compensation of the current used by energy consumers when showing
the vehicle (window regulator, heating, mirrors, etc) enabling permanent display of the vehicle
with power on.
These devices have an automatic restart feature allowing, in the Charge Mode and Showroom Mode,
to automatically restart the device in case of power cut.
The function "Showroom only", if activated, restricts the device to Showroom Mode only, to facilitate
its use for vehicles demonstrators.
