First, EPS EPS (Emergency Power Supply) serves as an emergency power backup system, providing essential power support for critical equipment such as firefighting gear, municipal utilities, hospitals, industrial machinery, and more during a main power outage. Unlike traditional backup generators, EPS systems excel in quick startup times, reduced noise levels, enhanced maintainability, superior power quality, overload capacity, robust self-protection mechanisms, and minimal environmental impact. EPS systems are categorized into three primary types based on their load types: lighting type, power type, and combined lighting-power type. These correspond to lighting loads, motor-driven equipment (such as fire pumps), and hybrid loads combining both lighting and motors. Second, the inverter plays a crucial role in the EPS power supply industry. When the main power supply fails, the inverter within the EPS takes over, converting stored DC energy from batteries into stable AC output to drive connected devices. This ensures uninterrupted power flow, maintaining the same quality as standard mains electricity. EPS systems rely on battery packs for power, meaning the inverter’s auxiliary power source must operate on DC rather than AC. Consequently, fans used for cooling and contactors for soft starts must also utilize DC components, ensuring compatibility with the overall DC-based design. The output voltage quality of an EPS is another key factor, especially in critical applications. Important considerations include the harmonic distortion of the output voltage, voltage regulation under varying load conditions, and overall voltage stability. A well-designed EPS should minimize fluctuations in output voltage, whether due to load changes or variations in battery pack voltage, while keeping harmonic distortion to a minimum. In highly sensitive environments, EPS systems require strong start-up capabilities. For instance, when battery voltages drop below typical thresholds, the inverter must continue operating normally and maintain sufficient output voltage and current, avoiding fault reports related to low voltage. Third, the development of specialized EPS inverters remains limited in the market. Many existing models come at premium prices from select brands. Recognizing this gap, Ziri Electric Technology Co., Ltd., leveraging over a decade of inverter manufacturing expertise, has launched the next-generation cost-effective ZVF9V-E series EPS-specific inverter. This innovation addresses the unique demands of the EPS industry, enhancing overall system performance. Key features of the ZVF9V-E series include: 1. Direct DC power supply capability eliminates the need for additional wiring. Its auxiliary power supply, cooling fans, and soft-contact components operate without requiring separate AC power sources. 2. Available in two voltage ratings—DC 500V and DC 300V—with respective power ranges of 1.5KW–315KW and 0.75KW–110KW. 3. High-frequency PWM technology ensures near-sinusoidal output waveforms with low harmonic distortion. The inverter also includes automatic voltage regulation, stabilizing output voltages despite fluctuations in battery pack voltage. 4. Adjustable undervoltage points between DC 360V and 480V, and overvoltage points between DC 660V and 760V, accommodating diverse customer requirements. This advanced inverter represents a breakthrough in the EPS field, offering reliable, efficient, and cost-effective solutions tailored specifically for emergency power applications.
