In today’s digital world, reliable power for critical systems is vital. Businesses, hospitals, and home offices depend on it. From data centers to communication networks, uninterrupted power is a must. A single phase high frequency online UPS is a compact, efficient, and high-performing choice. This article explains why it’s a smart option for protecting sensitive electronics.
A single phase high frequency online UPS is an advanced power backup system. It delivers steady, clean electricity to connected devices. It uses double conversion technology. This means it converts incoming AC power to DC and back to AC. This ensures stable output despite input fluctuations.
RM series high frequency online UPS is designed for servers, data centers, sensitive electronics, telecom, banks, hospitals, offices, traffic systems, security, and ATMs.
The system includes a rectifier/charger, battery bank, inverter, static bypass switch, and control circuits. During normal operation, it converts AC to DC to charge batteries. Then, it converts DC back to AC for output. This isolates devices from power grid issues.
True online double conversion with advanced microprocessor control ensures steady voltage and frequency.
Unlike offline or line-interactive UPS systems, which activate batteries only during outages or voltage issues, an online UPS always powers devices through its inverter. This avoids delays in switching. It offers better protection against power problems like surges, sags, harmonics, or frequency changes.
Zero transfer time between mains and battery mode makes it perfect for critical applications.
A key benefit is its ability to provide continuous power. The double conversion system ensures no delays during outages or voltage changes.
Transfer time is 0 ms. Switching from inverter to bypass takes less than 4 ms. This ensures smooth operation for sensitive systems.
High frequency models are smaller than low-frequency ones. They use modern semiconductor technology.
A 19” rack-mount design saves space. It’s ideal for server rooms or telecom closets with limited space.
These systems provide precise voltage control. They protect against low or high voltage. They also deliver a clean sine wave output, even with varying loads.
Voltage options are 110/115/120Vac or 220/230/240VAC ± 2%. This ensures reliable performance across regions and standards.
High efficiency reduces energy use. It also lowers heat output, cutting operating costs.
Efficiency reaches 95% and up to 98% in ECO mode. This saves on electricity bills while maintaining reliability.
The core feature is true double conversion. It isolates devices from power grid issues. It delivers pure sine wave output at all times.
High frequency online double conversion ensures clean power, no matter the grid conditions.
Traditional UPS systems may have delays when switching to battery mode. High frequency online UPS units avoid this.
Zero transfer time between modes is critical for medical equipment or financial trading systems, where every millisecond counts.
These UPS units are designed for delicate devices. They include active power factor correction (APFC), wide input voltage range, auto-sensing frequencies, and smart fan control.
APFC achieves an input power factor of 0.99. This reduces harmonic distortion for connected devices.
Users can choose internal batteries or external packs for longer runtime. Hot-swappable batteries allow maintenance without shutting down.
Rack-mount battery packs extend backup time. This offers flexibility based on operational needs.
Safety is built in. Overload protection ensures stability under high demand. Surge protection guards against lightning or electrical faults.
Protection against overvoltage, overload, overcurrent, and overcharging keeps the UPS and devices safe.
Advanced models have LCD displays for real-time status. Audible alarms alert users to issues. Intelligent slots support SNMP cards for remote monitoring.
Smart RS232 communication with monitoring software lets admins track performance remotely. Optional AS-400 dry contact and SNMP card add remote control options.
A single phase high frequency online UPS system offers unmatched reliability. Its compact design and advanced features suit critical applications. Whether for a hospital’s ICU or a company’s network, it ensures peace of mind with steady, clean power and smart management tools.
