What makes the difference ?

Our VRLA Gel deep cycle batteries are conform to the cycles use test norm IEC61427. The batteries still provide 100% of the full capacity in Ampere-hour (Ah) after 148 cycles.

Our Gel deep cycle batteries use high-tin alloy grid which increase corrosion resistance of plates and lengthen the service life. High-tight assembly technics, they accept very high charge and high current discharge performance. 

In combination  with our Hybrid Solar UPS solutions, the battery offers the best possible performance. For standart UPS application , the battery has a design lifetime of 10-12 years. 

Fast test for maintenance

The “fast test” takes only 10-15 sec. According the discharge curve, the analyzer gives you a clear result of the battery status and save all results to the internal memory.

Monitoring software included

The monitoring software (for windows, linux and mac) gives you the informations about the battery.  You can export and print this report or simply save in the internal memory of the analyzer.

The OPZv batteries designed for long lifetime and have excellent deep cycle performance. 

2V Cells or mounted as 12V blocks

Fully compliant with IEC 60896-11 & DIN EN 60254-2

Design life up to 20 years for 2V cells

Made in Germany

Temperature compensation of load

To preserve the long life of our batteries, it is advisable to compensate the charge voltage in floating to room temperature. The focus is to 2.275V / cell and 20 ° C, we recommend - 3 mV / ° C for temperatures above 25 ° C and + 3 mV / ° C for temperatures below 15 ° C. It will be necessary to add the optional temperature probe and to  placed it close to the batteries.

AUNISOLBAT batteries 12ET-L series are used specifically for the inverters, rectifiers battery chargers and central sources of security lighting. The tight construction of the battery allows operation without problems in all positions. Since No specific maintenance and servicing is required with an operation based on the principle of the gas recombination (99%).

The revolutionary energy storage

The carbon battery is based on the lead acid technology. Unlike lithium batteries standard lead acid batteries have a big discharge capacity (up to C3*). Indeed, a much longer charging time (up to 10 hours, =0,1) must be accepted to prevent sulfatization which would shorten the lifetime of the battery. The new carbon technology provides a solution for this problem: Using carbon guarantees much less sulfatization of the negative electrode. Thus, the battery can be charged up to 3 times faster (=0,3C) than a standard lead acid battery.

Modern lithium battery sytems can also be charged within less than an hour, but the discharge capacity is very low: It must not exceed 50-70% of the battery capacity (= C0,5-07).

The fast charging is a significant progress in thecarbon technology, since the charging current for the daily cycle mode can be adjusted at 20-30% of the battery capacity (= 0,2-0,3C). Therefore, it is possible to recharge a discharged battery within 1-3 hours.

Protection against power supply failures

Protection against power supply failures

The MultiNET_STS static transfer switch 63A/120A is designed for 19" rack cabinet. Can be powered with 2 differents UPS and provides protection against load and power supply failures.

Redundant system

Power is supplied by 2 separate supply circuits that are fully independent and that can be replaced during normal operation (hot replacement mode)  without any risk of causing power supply interruptions to the load. In the unlikely event of a failure at one of both power supplies, the full operation is provided by the “Power Supply backup” function, which offers auxiliary power supply to the circuits from an external, independent power source. The MultiNET_ATS is equipped with a redundant ventilation system.

Working principle

The MultiNET_ATS allows the load to switch between alternative and independant power sources for guaranteed redundant power. The switch can be automatic (when a source falls outside the acceptable tolerance) or manually through the front panel control.

Relay cards are based on dry contacts and give signals in the case of power supply interruption, switching to bypass or general faults. The AS400 and Modbus card provide the interface for the corresponding protocols.

SNMP adapters provide monitoring of the UPS via ethernet or WLAN including email notifications. The monitoring software allows connection with the IP adress of every UPS. For example all servers in a network can be shutdown. SMS can be sent without LAN connection by using a GSM modem.

The report defaut is physically connected with the UPS by cable and allows distant monitoring and management of the system. The panel can be installed as far as 500m from the UPS and will be power supplied by the interface cable.

With the galvanic isolation transformer the electric circuits before and after the UPS are not connected physically but via an electromagnetic field. This increase the reliability of the protection. Spikes and disturbances can not pass the galvanic isolation transformer.

External manual bypass modules (singlephase & threephase) allow service and maintenance work without interruption of the power supply. The UPS can be disconnected after the power supply was switched to the bypass line. All the Aunilec MultiNET_ATS range can be also used as external bypass.

External and internal chargers for batteries of higher capacity and faster charging time.
