Critical Model Differentiation – IB vs External Battery Version

There is significant marketplace confusion between Microtek’s internal battery (IB) and external battery configurations. This listing is for the NM36MX1KK11-IB, which is the INTERNAL BATTERY VERSION. Key differentiators:

• This Product (NM36MX1KK11-IB): Contains 3 x 12V / 7Ah batteries INSIDE the UPS. Weight 12.5 kg. Charging current 0.7-0.8A. 2 YEARS WARRANTY. Complete, standalone, plug-and-play.
• MAX+ External Version (NM36MX1KK11): NO internal batteries. Requires external 36V battery bank. Weight 7.8 kg. Charging current 9.5A. 2 years warranty. For customisable runtime with external batteries.

Choose this IB version for compact, all-in-one deployment with standard backup time. Choose the external version if you require extended runtime with large external battery banks. Browse our full selection of Microtek UPS systems and power backup solutions to compare models.

True Online Double-Conversion Technology

The NM36MX1KK11-IB employs genuine online double-conversion topology using high-frequency IGBT/MOSFET-PWM technology with micro-controller based design. The rectifier converts incoming AC mains to regulated DC power, simultaneously charging the internal battery bank, while the inverter continuously converts DC back to clean, stable pure sinewave AC power for connected equipment. Transfer time is zero from AC mode to battery mode and less than 4ms from inverter to bypass mode – your critical loads remain operational through every voltage sag, spike, surge, or complete blackout without interruption.

Integrated Battery Bank – 36V / 7Ah x 3

This UPS ships with three 12V, 7Ah SMF-VRLA (Sealed Maintenance-Free – Valve Regulated Lead Acid) batteries pre-installed and factory-connected in series to form a 36V DC bank with total capacity of 252VAH. The batteries conform to JISC:8702 standards and are specifically designed for UPS duty cycle applications. The integrated 0.7-0.8 Amp trickle charger maintains battery health through an advanced three-stage charging algorithm (bulk, absorption, float), with automatic battery charging function even when the UPS is in off mode. Typical backup time at 50% load (450W) is approximately 10-15 minutes; at full load (900W), approximately 5-8 minutes. Actual backup time varies based on load, battery age, ambient temperature, and charge state.

Inbuilt Over Voltage Cut-Off Device (OVCD) and Comprehensive Protection

The NM36MX1KK11-IB incorporates an inbuilt Over Voltage Cut-Off Device with integrated surge protection. This critical safety feature continuously monitors incoming mains voltage and instantly disconnects the UPS if unsafe voltage levels are detected, safeguarding both the UPS unit and your sensitive connected equipment from damage. Comprehensive protection suite includes:

• Short Circuit Protection: 5 cycles turn off inverter, no transfer to bypass, audible alarm (AC mode); 5 cycles turn off inverter, audible alarm (battery mode); input fuse blown or breaker action
• Overload Protection: >110%: 30 seconds transfer to bypass mode; >150%: instant transfer to bypass mode
• Over Temperature Protection
• DC Fan Failure Protection
• EMI/RFI Noise Filter
• Low Battery Cut-Off
• Static Bypass (Enable/Disable)

Technical Specifications

Advanced Features and Benefits

The NM36MX1KK11-IB incorporates Microtek’s Advanced PFC (Power Factor Correction) technology, maintaining input power factor above 0.99 at full load for reduced harmonic pollution and improved energy efficiency. Advanced Battery Management system continuously monitors battery health and optimises charging parameters to extend battery service life. The UPS is fully generator-compatible, with wide input voltage and frequency windows that accept power from standard sinewave generators even when output voltage and frequency fluctuate.

Smart RS232 communication with included monitoring software provides real-time status, event logging, and graceful shutdown capabilities for connected servers and workstations. An optional SNMP card slot enables advanced network management integration. The UPS is specially designed to suit Indian power and environmental conditions, with robust construction and thorough testing including dry heat, damp heat, and cold tests per IS:9000 standards.
