Product Description
13.8V/2A/7AH buffer power supply PULSAR HPSB-12V2A-B
![](galerie/z/zasilacz-buforowy-13-8v-2a-7a_69996.jpg)
HPSB-12V2A-B - impulse buffer power supply is designed for uninterrupted supply to devices requiring stabilized voltage of 12 V DC (±15%). In case of mains voltage decay, there is an immediate switch to battery supply. The power supply has been constructed based on pulse power supply modules with high energy efficiency and are housed in metal enclosures (color RAL 9003) with space for battery(ies). The enclosures are equipped with a microswitch that indicates the opening of the door (tamper).
Main features of the HPSB-12V2A-B power supply:
- power supply voltage ~200 - 240 V
- uninterruptible DC power supply 13.8 V; 27.6 V or 54 V
- available versions with space for batteries from 7 Ah to 65 Ah
- high efficiency (up to 90%)
- battery charging and maintenance control
- optical LED signaling
- battery protection against over-discharge (UVP)
- battery output protection against short-circuit and reverse connection
