MHPower WPU-300-12, UPS, 300W, pure sine, 12V SET with 33Ah battery

Product detailed description

Discounted MHPower backup power supply and 33Ah  battery set;is ideal as a backup source for a circulating pump, as a backup source for a boiler or as a backup source for a fireplace stove. However, thanks to its clean output sine curve and robust toroidal transformer, it is also suitable for backing up many other devices such as household appliances, power tools, chargers, compressors, pumps, motors, electric drives, office equipment, television equipment, telecommunications, servers, PCs and other powered devicesup to 300Wcontinuous operation. The backup power supply can also be used as a UPS for a caravan.The biggest advantage of this set is the possibility of connecting an external battery (33Ah AGM battery included), which makes it able to power the connected appliances for a long time depending on the consumption of the appliance.

Example: The circulator with a continuous power input of 50W can be backed up by this assemblyup to 6.5hrs. More information can be found in the orientation table in the product gallery.

Features:
When the mains power is supplied, the connected appliances are powered directly from the mains, the external battery is recharged, when the mains fails, the power supply automatically switches to the voltage converter, energy is drawn from the battery, the appliances are powered from the converter. When power is restored, the power supply automatically switches to the mains, the battery starts to recharge.

ATTENTION! The backup power supply (UPS) only works when connected to an external battery. It should not be used without the battery connected. Once the battery is connected, plug the main power cord into a mains socket (230V, 50 Hz) with a mains earth connection. On the back of the power supply, connect the device you want to operate during a power failure. Follow the following procedure: connect the battery, connect the main power supply, and then connect the appliance(s) to the backup power supply (UPS).To switch the AC load (appliance sockets) on or off, press and hold the power button (ON/OFF) for about 2 seconds.

In the event of a power failure or if the power parameters are not within the normal range, the backup power supply (UPS) automatically switches to the battery. The switching of the UPS to the battery is shown on the UPS display. The UPS device also announces the switching of the UPS to the battery with an audible signal.

Description of the MHPower 33Ah backup battery:

Designed for backup power and UPS applications, MHPower lead-acid batteries are characterized by high quality, reliability and long service life. The low internal resistance makes them suitable for use in devices with high discharge currents such as inverters, starters.

These are sealed lead-acid batteries in VRLA design. The advantages of this design, together with AGM (Absorbed Glass Mat) technology, are mainly as follows:
- higher maximum discharge currents
- maintenance free
- longer service life
- shockproof
- leakproof - sealed - unbreakable

MHPower lead-acid batteries are suitable as replacement batteries for electronic systems and especially for the following applications:
- backup power supplies (UPS)
- electronic fire protection systems (EPS)
- electronic Security Systems (ESS)
- telecommunications equipment
- emergency lighting
- geophysical, meteorological and medical instruments and equipment
- backup of circulators and boilers

Hermetically sealed, maintenance-free.
Long life, low self-discharge.
 

Battery warranty 2 years. Service in the Czech Republic.
