KEMSAN KPR Model Rectiﬁers have 2 diﬀerent types of charging Batteries. These are Buﬀer and Balance Charge Mode.
Buﬀer Charge:charging the battery until it reaches the speciﬁed Buﬀer Charge value from battery catalog. This value is typically between 2.25V and 2.30V for 2 V cell batteries.
Balance Charge: charging the battery until it reaches the speciﬁed Balance Charge value from battery catalog. This value is typically between 2.40 and 2.50V V for 2 V cell batteries.The Balance Charge should not be applied too often; instead, it should be applied speciﬁed frequency and period as described in battery catalog. Keeping the batteries at Balance Charge too much may damage them.The voltage values of Buﬀer and Balance Charge can be adjusted from front panel and it provides the user to adjust them for diﬀerent cell and battery types.
Kemsan KPR Model Rectiﬁers have two types of charging speed; Regular and Boost Charging. These types can be selected from front panel.
Regular Charging: Charging batteries at regular charging current value which is determined by the battery catalog. In general, the Regular Charging Current is calculate as 0.1CA
(1/10 of Battery capacity) as detemined by the battery catalog.
Boost Charging: to charge the battery at boost charging current value determined on battery catalog. In general, the Boost Charging Current is calculated as 0.25CA (1/4 of Battery capa- city), as determined by battery cata- logs. Boost charging should be done within the time as speciﬁed in the battery catalog. Regular and Boost charging currents may vary depending on battery types. Therefore, the values must be set by carefully examining the battery catalogs and datasheets.
With our KPR model rectifiers, All values of the unit can be observed or adjusted via LCD front panel.The user can monitor the Values of the Input Voltage, Frequency of the Current, the Output Voltage and Current, Transformer and Heat-sink temperatures. The status of the rectifier can easily be monitored through the graphical diagram located on the device control panel. Abnormal situations that occur on the unit can be monitored through the warning indications on the graphical diagram, and the device can be stopped if necessary. On request of user, additional analog or digital voltmeter, frequency meter and ammeter can be added to the front panel.
It is used for remote monitoring and control of rectiﬁers. It is used for remote monitoring and control of rectiﬁers.
OVERLOAD/ SHORT CIRCUIT PROTECTION
Kemsan KPR Model Rectiﬁers have a standard Current Limiting feature. The current is limited by reducing the output voltage up to a maximum of 125% of the allowed current. Thus, overload and short circuit protection are provided. In addition to electronical protection, for extra protection circuit breakers that can be controled by DC voltage are used
