Wanna See Specs For A REAL Battery Charger?

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
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.
• Dv/dt Termination - Precise termination that tracks rates of change of battery voltage (dv/dt), or you can select time-voltage (t/v) termination.
• Manual Equalize - Provides user control to start or stop an equalize charger.

• Easy to read LED Indicators
•Charging
•80% Indicator
•Charge Complete
•Equalize
•Power ON



POWERGUARD™ HD & LD Control Your Battery Fleet
POWERGUARD' HD & LD guards your battery fleet against being over or under charged. See the POWERGUARD™ difference ...

• In the case of an AC power failure, the charger resumes charging exactly where it stopped charging

• Backup timer and second, separate timer initiate a 15-hour
countdown when the charge cycle begins. Should the primary timer fall. the backup timer shuts off the charger 15 hours after it starts.

• Solid-state electronics perform self-diagnostics on the charger and shut it down in case of charger-related problems.
The PREMIUM Control offers:
• All the features of the PRO Control
PLUS-
• Programmable equalize - Allows you to program the duration and frequency of equalize.
• Programmable delayed start - Delay period can be adjusted from 0 to 25 hours, in 6 minute increments.
• Programmable cool down - Allows you to program the cool down tune between 0-12 hours.
• Auto refresh - A refresh charge is performed every 12 hours for 20 minutes.
• Programmable refresh charge time limit - Allows you to program both the duration of charge (from 0-60 minutes) and the charge interval (from 2-24 hours)
• Programmable post 80% limit - May be programmed to run from 0-10 hours after reaching 80%.
• LED numeric display - Four digit/seven segment numeric display shows the volts per cell. AH returned, delay time. total charge time and fault condition by fault mode.
• Faults - The charger control circuitry constantly monitors for eleven different fault conditions.
• Random restart on power failure - After a power outage, upon power restore, the charger(s) will have a random short delay before restarting. to prevent a power surge.

POWERGUARD™ HD allows you to control your fleet operation while at the same time control your operating costs.
POWERGUARD™ LD
POWERGUARD™ LD chargers are rated to return an 80% discharged battery to full charge in eight hours and should not be used in applications where overdis-charging may occur. POWERGUARD™ LD is designed for light duty applications and is available in both single and three-phase.

The POWERGUARD™ LD charger is only available with the standard (PRO) control board.

POWERGUARD™ LD features:
• Choice of dv/dt or time-voltage termination
• Auto Start/Stop
• Manual Equalize
• Easy to read LED Indicators
  • What no Pictures , come on some one needs to know. :B

    Actually my son a real mechanic, has a charger that is a doozer. He got it from one of the Mac Tool trucks at his shop, and NAPA has them also.

    • 20/10/2A charge rates
    • 20A fast charge rate is ideal for charging
    large batteries
    • Fully automatic operation
    • Advanced multi-phase charging process
    • Properly charges all battery types
    • Soft Start Mode for severely depleted batteries
    • Recondition Mode rejuvenates
    distressed batteries
    • Enhanced maintenance mode for ideal long
    term storage
    • Temperature compensation for more
    effective charging
    • Reverse Polarity Protection and Battery
    Fault Detection
    • Data rich display provides detailed feedback
    during charging
    You hook up your single battery ( and has settings for just about every kind) , set on 2 amp charge, and leave over night. This thing charges and then goes through the whole battery,checks for bad spots and either fixes it or lets you know it is bad.

    Then do the other one/s the same way. It takes a while and great re-charge on the batts. You have to have a patience.

    As usual all disclaimers and Buyer beware.
    Yeh I couldn't copy the picture either.:S
  • I'm not sure if a ferroresonant design would be my first choice for battery maintenance- I would go for the Powertech high frequency model.
    I would be interested in how they control the voltages on the FR model- as I understand it, ferroresonant are inherently a single voltage design, though they obviously control it somehow, or just turn it on and off.
