Zener ZL

Zener ZL line-interactive single phase to single phase UPS

The ZL UPS, with a capacity of 1500 VA, is a single-phase Line-Interactive uninterruptible power supply system designed to protect personal computers and office equipment from power fluctuations. This model offers stable performance with an input/output voltage of 230V (±10%), a frequency of 50 or 60 Hz, and a switching time of 4 to 8 milliseconds. Equipped with AVR technology, it provides stabilized output voltage for connected devices; the integrated stabilizer with a wide operating range enhances system efficiency during grid power fluctuations. Two internal 12V 9Ah batteries provide a backup time of 6 to 8 minutes at full load. The LCD display clearly shows key parameters such as input/output voltage, battery level, load percentage, and UPS operating status. The rear panel, featuring an AC input socket and four output sockets, allows easy connection to devices, while comprehensive protections against overcurrent, overvoltage, overtemperature, and deep battery discharge enhance safety. Its compact design, with dimensions of 198 × 380 × 158 mm and a weight of approximately 14 kg, facilitates installation in confined spaces. The audible noise level below 55 dB ensures a quiet environment. Audible alarms for low battery, overload, and faults keep users informed. Internal battery replacement is straightforward. The installation and setup of this UPS require minimal technical knowledge, and the end user can set it up using the included manual. The ZL UPS, with its focus on simplicity and low cost, is a cost-effective solution for home and office users.
