Who is the official importer of this UPS in Bangladesh?
A: TNS Engineering Ltd. is the official importer in Bangladesh.
What type of UPS is it?
A: It is an online UPS (double conversion) with zero transfer time during power outages.
What is the power rating of this UPS?
A: The UPS offers 10 kVA / 9 kW power output.
What is the input voltage range?
A: It accepts 165–275V AC with ±25% tolerance.
What is the output voltage regulation?
A: Output is maintained at 220/230V ±0.5%, ensuring stable power for sensitive devices.
What battery configuration does it use?
A: The UPS uses 16 × 12V batteries (internal or external, 9Ah–200Ah).
Can external batteries be connected?
A: Yes, external batteries of higher capacity can be connected for longer backup times.
How long does the UPS provide backup?
A: Backup time depends on load and battery size—standard internal batteries provide around 10–15 minutes at full load, while larger externals can extend it to several hours.
What is the recharge time of the batteries?
A: Batteries typically recharge to 90% capacity within 8 hours.
Does it support hot-swappable batteries?
A: Yes, depending on configuration, batteries can be replaced without shutting down the system.
What is the transfer time between mains and battery?
A: Zero milliseconds (0ms) because it is an online double-conversion UPS.
What is the efficiency of the UPS?
A: Up to 89% in AC mode, 85% in battery mode, and 94% in ECO mode.
What protections are built-in?
A: Overload, short circuit, overvoltage, undervoltage, battery failure, and over-temperature protection.
What is the overload capacity?
A: It can handle 125% load for 1 minute and 150% load for 200ms before shutdown.
Does it protect against surges and spikes?
A: Yes, it has built-in surge protection and AVR for stable voltage.
Where can the DRESDEN-LF1110 UPS be used?
A: Suitable for data centers, telecom, servers, medical equipment, banking, and industrial applications.
Is it compatible with generators?
A: Yes, it works efficiently with diesel or petrol generators.
Can I use it for home appliances?
A: While possible, it is primarily designed for industrial, commercial, and IT environments.
Is it suitable for sensitive equipment like medical devices?
A: Yes, the stable pure sine wave output makes it ideal for critical equipment.
Can it run air conditioners or motors?
A: It can run small motors within its rating but is not recommended for heavy inductive loads.
What communication ports are available?
A: RS232 (standard), with optional SNMP and dry contacts.
Is remote monitoring supported?
A: Yes, through an SNMP card and monitoring software.
Does it have an LCD display?
A: Yes, it comes with an LCD panel for status, fault, and battery indicators.
Can alarms be configured?
A: Yes, audible and visual alarms are provided for faults and battery status.
Can I monitor the UPS via network?
A: Yes, with an SNMP adapter, it can be monitored via LAN/WAN.
What is the operating temperature range?
A: 0°C to 40°C with humidity up to 95% (non-condensing).
What is the noise level?
A: Less than 55 dB at 1 meter distance.
Does it require special installation?
A: It should be installed in a ventilated, dust-free, and temperature-controlled environment.
Can it be rack-mounted?
A: This model is typically tower type, but rack options may be available
