Microtek-Online UPS MAX-2KVA 72V Pure Sinewave with in-Built Batteries UPS
Microtek’s MAX‑2KVA 72V Online UPS with built‑in batteries is a high‑performance, pure sine wave double conversion UPS designed for critical applications. With a rating of 2 kVA (≈1800 W), solid 72V battery system (6 × 12V 7Ah), wide input voltage tolerance, fast switching, LCD/LED interface, and protections against overload, short‑circuit, and temperature fluctuations, it provides reliable, clean, uninterrupted power backup for servers, networks, labs, or home setups.
Rated Capacity: 2 kVA / 1800 Watts, suitable for moderate to heavy loads.
Built‑in Battery Setup: Comes with 6 SMF/VRLA batteries, 12V 7Ah each, in a 72V configuration.
Pure Sine Wave Output: Ensures clean AC output suitable for sensitive electronics.
Online Double Conversion Technology: Converts AC→DC then DC→AC to provide clean, regulated output and isolates load from input disturbances.
Wide Input Voltage Range: Capable of operating normally over a wide AC input range; for lighter loads <50% the range is about 118–295 V, and for heavier loads >50% more limited (≈160–295 V).
Frequency Range (Input & Battery Mode): Accepts wide input frequency (≈40‑70 Hz), battery mode output around standard 50Hz ± tight tolerance (or 60Hz in some versions).
Fast Transfer / No Break: AC to battery / inverter to bypass switching is very fast, typically under 4 ms or “zero” delay in many specs.
Output Voltage Selections: Can be set / delivers common AC voltages (208V, 220V, 230V, 240V) to match the region/equipment.
High Efficiency: Efficiency in normal conditions lies roughly between 85‑92%.
Protection Features: Overload protection (e.g. >110% load triggers bypass after ~30 seconds; very high overload (>150%) possibly immediate bypass), short circuit protection, over temperature protection.
Surge & Over‑Voltage Cut‑Off Device (OVCD): Protects against high voltage spikes; “surge protection & in‑built over voltage cut‑off device.”
Display & Monitoring: Smart LCD (and/or LED) display to show real‑time parameters, load, battery status; communication via RS‑232, optional SNMP card for remote monitoring.
Generator Compatibility: Can work with generator inputs; also includes EMI/RFI filters for noise suppression.
Physical & Weight Specs: Approx dimensions ~ 56 × 32 × 46 cm (D × W × H) in some listings; weight approx 25‑30 kg (varies if batteries in‑built).
Warranty & Service: Generally 24 months for UPS unit, battery warranty often shorter (≈12 months) for built‑in batteries. After warranty, battery maintenance / replacement will be important
