POWERGUARD™ HD
The Power To Choose
The POWERGUARD™ HD charger series is HAWKER's new ferroresonant
charger line.
The POWERGUARD™ HD charger series consists of single-phase
and three-phase chargers for every charging need. POWERGUARD™
HD features stackable drip-resistant cabinets and are designed to
be convection cooled in ambients up to 40°C (104°F).
Hawker offers two different models in the POWERGUARD™ ferroresonant
line, the POWERGUARD™ HD (for heavy duty applications) and
the POWERGUARD™ LD (for light duty applications). Let's take
a closer look at the two models.
POWERGUARD™ HD is designed to return a 100% discharged
battery to full charge in eight hours or less; everything from
a 6, 12, or 18 cell battery all the way up to a 24 or even a 40
cell battery. With an 18% start rate and 4 to 5% finish rate,
the POWERGUARD™ HD chargers are built to return 108% to
112% of your battery's rated capacity in an eight-hour period.
The POWERGUARD™ HD charger is available with two different
controls, the PRO and the PREMIUM. You can select the control
that best meets your charging needs.
The PRO Control offers:
• Auto Start/Stop - Auto start/stop enables
the charger to start/stop the charge cycle automatically.

that tracks rates of change of battery voltage (dv/dt), or you
can select time-voltage (t/v) termination.
