PRODUCT DESCRIPTION
MUST EH9335 10KRS 10KAVA Rack Mount Online UPS in Bangladesh
MUST EH9335 10KRS is a 10KVA/9KW high-frequency, single-phase online UPS in a rack mount design, engineered for mission-critical power protection in enterprise environments. It ensures reliable and clean power delivery for data centers, servers, medical systems, and industrial equipment. With three-phase input/output and an output power factor of 0.9, this UPS supports even the most demanding electrical loads with ease. This advanced UPS supports a wide input voltage range (208–478V) and includes automatic frequency sensing, making it highly adaptable to fluctuating grid conditions. The output voltage remains precisely regulated at ±1%, while harmonic distortion stays under 2% for linear loads, ensuring stable and clean output. Equipped with zero transfer time (0ms) during power switching, high efficiency (94.5%), and ECO mode support, the EH9335 maximizes uptime and minimizes energy waste. It supports parallel redundancy (up to 4 units) for scalable power protection, and its robust overload and thermal protection mechanisms ensure uninterrupted performance. The battery system is flexible, supporting 192V to 240V DC configurations (default: DC±192V), with a maximum 10A charging current. Communication interfaces include RS232, RS485, and optional SNMP, providing seamless integration into remote monitoring systems. Despite its powerful performance, the unit remains compact at just 580×443×131 mm and 32 kg, making it ideal for rack installations in professional IT setups.
Can the MUST EH9335 10KRS UPS be monitored remotely?
Yes, it supports RS-232, USB, and optional SNMP or RS485 communication.
Is this UPS suitable for sensitive devices like servers?
Absolutely. With 1.0 power factor, low THD, and 0ms transfer time, it's ideal for servers.
What battery types are supported?
It supports 7Ah lead-acid batteries with flexible charging modes and current settings.
