POWER PEAK ULTIMATE - Battery charger ROBBE - Free user manual and instructions

USER MANUAL POWER PEAK ULTIMATE ROBBE

The POWER PEAK ULTIMATE is designed for charging and discharging NICD and NIMH batteries consisting of 1 to 25 cells, both in automatic mode with automatic current setting, and in manual mode. The charge process is terminated by the Delta Peak method when the battery is fully charged.

The unit can also charge lead-acid batteries (2 to 12 Volts) automatically.

The charger features 10 spot memories in which you can store settings which you have entered for each battery in manual mode.

Safety notes

• If the charger is not to be used for a protracted period, disconnect it from the power source and remove any battery packs connected to it.
• Be sure to keep the cooling slots unobstructed to provide good air circulation - don't stand the charger on a carpet or felt surface.
• Do not set up the charger and batteries on a flammable surface, and never leave the unit operating unsupervised.
• Protect the unit from damp.
  Take care to maintain correct polarity at all connections and outputs.
• Avoid short-circuits.
• Don't subject the charger to direct sunshine, and do not cover it.
• Do not charge batteries which are already hot; allow them to cool down to ambient temperature before recharging.
• Use only packs of fast-charge cells which have been properly balanced (equal state of charge).
• Packs must consist of cells of the same make, type and capacity.
• Do not wire two packs together in parallel for charging.
• The unit is only suitable for use with rechargeable batteries.
• Set charge currents within the maximum rated capacity of the cables and connectors attached to the battery pack.
• Never connect any charger output to the input.

If you press the MODE button repeatedly you can switch between CHARGE, DISCHARGE and DISC/CHAR for NICD and NIMH packs separately.

• Press the START button to initiate the selected process.
• The screen displays capacity, time, voltage and current. The status (C=CHARGE, D=DISCHARGE, F=FINISHED) is displayed at top left of the screen.

• The charge or discharge process is ended by the automatic termination circuit or by the operator pressing the STOP button.

MANUAL MODE

Before you can start the actual charge or discharge process, you have to set the battery type (NICD, NIMH or PB), the cell count, the battery capacity, the charge current and the discharge current.

Up to ten such sets of parameters can be stored in spot memories 0 to 9 and called up at any time. The setup menu required for this appears immediately when you select manual mode.

Note: you can only change values in the first line when the arrow symbol is flashing.

General information about charging and discharging batteries

As a basic rule please be sure to observe the battery manufacturer's recommendations, especially the information regarding maximum charge currents.

To ensure that the automatic Delta Peak circuit is able to work as efficiently as possible, only properly balanced packs should be fast-charged. This means that new packs, and packs which have not been used for a long time, should be discharged at regular intervals and re-balanced by slow-charging at a low rate, typically C/10.

An occasional complete discharge process also helps to avoid and/or eliminate the MEMORY EFFECT.

Fairly old batteries, and packs of certain relatively low-quality cells, may prevent the automatic current setting function working properly in automatic mode. In such cases we recommend that you use manual mode.

Charging and discharging a transmitter battery which is installed in the RC system transmitter is only possible if you either by-pass the protective diode in the transmitter's charge circuit, or remove the battery from the transmitter and connect it to the charger using a direct charge lead.

Conversion work on the transmitter should only be carried out by an expert, ideally by your nearest robbe Service Centre.

No. 8262

Notes

• The maximum charge and discharge currents vary according to the number of cells in the pack.
• Don't end the charge or discharge process simply by disconnecting the battery pack; always stop the process by pressing the MODE button.
• Lead-acid batteries can only be charged in manual mode.

Mains PSU

• If you use the Power Peak 7A mains PSU, Order No. 8415, the charger can also be operated from the 230 Volts mains supply, turning it into a universal 230 V AC and 12 V DC charger. Note that the maximum currents are restricted in this mode of operation when used with high cell counts.

Notes on RID (Radio Interference Directive)

In order to satisfy the conditions of the RID, the charge lead must be modified using the ferrite ring as shown in the sketch before you use the charger for the first time.

We reserve the right to alter technical specifications.
