MUST EH55-H1K2 1KVA Online UPS — Zero transfer time killing downtime today?
Power drops ruin servers, routers, and workdays. The MUST EH55-H1K2 1KVA Online UPS answers that pain fast. This online UPS keeps output steady during grid swings and blackouts. Offices and labs rely on it for constant uptime.
MUST EH55-H1K2 1KVA Online UPS overview for critical loads
This unit delivers 1KVA/1KW rated capacity with double conversion online design. Output never blinks during input failure. Sensitive electronics stay protected at all times.
The system handles wide input voltage. It runs clean across 110V to 300VAC. Frequency support covers 50/60Hz with tight tolerance. That range suits unstable grids found across Bangladesh.
Noise stays low at ≤45dB. Deskside and rack-side use feels comfortable. Compact dimensions fit tight server rooms.
Performance behavior under load
Load handling defines reliability. This UPS manages overloads with clear timing. In AC mode, it sustains 30 minutes at 102–110% load. Higher overloads trigger controlled protection. Battery mode follows defined limits to protect cells.
Zero output transfer time protects active sessions. No reboot. No packet loss. That matters for routers, NAS, and database systems.
Efficiency stays high. AC mode reaches up to 94.5%. Battery mode hits up to 88.5%. Power bills stay in check without sacrificing protection.
Power quality control with DSP and PFC
The DSP digital control engine keeps voltage tight. Output regulation holds within ±1%. Battery frequency accuracy stays within ±0.1%.
Active PFC technology improves input power factor. Cleaner draw reduces upstream stress. The design suits generator-backed setups common in local offices.
Harmonics remain controlled. Linear loads see less than 4% THD. That protects PSUs and network gear from heat stress.
Battery system and runtime expectations
This UPS uses lead acid batteries with a 24V battery bus. The standard pack includes 2×12V/9Ah batteries. An optional configuration supports 2 or 3 internal batteries.
At full load, expect 3–5 minutes of runtime. That window allows safe shutdown or generator start. Cold start works without grid input, helpful during total outages.
Charging supports adjustable current ranges. Recovery stays fast after discharge.
Monitoring and display control
The front panel uses a 2×8PIN, 128-bit segment code display. It supports up to four buttons and four LEDs. Operators read operating mode, load, and input/output status at a glance.
Clear indicators reduce human error. Technicians react faster during faults.
Connectivity and integration
Connectivity matters in managed environments. This UPS supports USB and RS-232 interfaces. SNMP comes as an option for network monitoring.
IT teams integrate it into monitoring stacks. Alerts trigger before batteries drain. That control suits data rooms and branch offices.
Electrical input and output characteristics
Input supports 208/220/230/240VAC nominal. Output mirrors those options for compatibility. Power factor wiring follows L+N+PE standards on both sides.
Transfer time lists 4ms, while the online design delivers continuous output without interruption. Protection circuits respond instantly during anomalies.
Physical build for space-limited rooms
The chassis measures 143 × 222 × 285 mm. Weight stays at 7.5 kg. Installation feels simple for single-person handling.
The compact form suits shelves, racks, and under-desk placement. Ventilation supports stable operation between 0°C and 40°C.
Use cases across UPS IPS & Power Solutions
Within UPS IPS & Power Solutions, this model fits many roles. Banks protect terminals. Studios protect workstations. Clinics protect diagnostic devices. Small data centers protect switches and servers.
The UPS sub-category demands constant output. This model meets that expectation without compromise.
Reliability, safety, and warranty terms
The unit carries a 1-year manufacture warranty. The box remains mandatory during claims. Proper environment matters.
Warranty excludes damage from thunder, abnormal overloads, insects, dust, or damp placement. Ambient temperature must stay 20–26°C with dehumidification running 24/7. Generator use requires proper battery charging. Incorrect system voltage causing battery swelling voids coverage.
These conditions protect long-term performance and battery health.

FAQs
Is the MUST EH55-H1K2 1KVA Online UPS suitable for servers and networking gear?
Yes. Its double conversion design delivers constant voltage with zero transfer time. That behavior suits servers, switches, firewalls, and NAS devices sensitive to power interruptions and frequency drift.
How long can the MUST EH55-H1K2 run during a power outage?
At full load, it supports around three to five minutes. Lighter loads extend runtime. This window allows safe shutdown or generator engagement during outages.
Does this UPS handle unstable voltage common in Bangladesh?
Yes. It accepts input from 110V to 300VAC. That wide range stabilizes output even during severe grid fluctuation common in urban and semi-urban locations.
What battery type does the MUST EH55-H1K2 use?
It uses sealed lead acid batteries with a 24V system. The standard setup includes two 12V/9Ah batteries, with optional internal expansion support.
Is the noise level acceptable for office placement?
Yes. Noise stays at or below 45dB. That level fits offices, studios, and labs without causing distraction during daily operations.
How does MUST EH55-H1K2 1KVA Online UPS compare with line-interactive UPS models?
Online UPS units deliver constant conditioned power. Line-interactive models switch during faults. This model avoids transfer delays, making it better for sensitive electronics.
Does it support cold start without grid power?
Yes. Cold start works from battery power alone. That feature helps during complete blackouts when grid input remains unavailable.
What interfaces are available for monitoring and control?
It supports USB and RS-232 by default. SNMP remains optional for network-based monitoring across enterprise environments.
What is the price and availability at PCB Store in Bangladesh?
Pricing varies with stock and configuration. PCB Store in Bangladesh offers local availability, warranty support, and updated pricing upon inquiry.
