Emergency power supply "Fuel Cell Hydrocube-LT"

Emergency power supply "Fuel Cell Hydrocube-LT"

The easily accessible "Fuel Cell Hydrocube-LT" that anyone can use freely anytime, anywhere! It demonstrates outstanding effectiveness as an emergency power source!

**Features of Hydrocube-LT in addition to the general characteristics of fuel cells (below)** ■ Hydrocube-LT is an upgraded version of ABIOS-1, increasing the stack power generation capacity from 100W to 150W, and allowing for the choice of power supply between DC24V or AC100V. This means that not only can lighting devices be freely selected, but other electrical appliances can also be used. ■ The Hydrocube series has renewed the design of the ABIOS series. ■ In the ABIOS series, fuel cells and hydrogen tanks are transported together using a dedicated carrier, but in the Hydrocube series, these are separated to distribute the load during transport. Additionally, the fuel cell casing has been made smaller, making it even easier to transport. A carry handle for the fuel cell and a tank carrier for the hydrogen tank are available as options. ■ The Hydrocube series has made it easier to use large hydrogen tanks. The Hydrocube-LT operates for over 12 hours with a single 10L tank. By replacing the tank, even longer power generation is possible.

Partial Resonant Inverter (NH) + Magnetic Amplifier Output Circuit

Partial Resonant Inverter (NH) + Magnetic Amplifier Output Circuit

A consistent production system from design and manufacturing to after-sales service! Let us introduce our circuit configuration.

We would like to introduce our "Partial Resonant Inverter (NH) + Magnetic Amplifier Output Circuit." The "Partial Resonant Inverter (NH)" is a circuit configuration that achieves reduced switching losses and low noise. The circuit resonates partially only during the turn-on/off of the inverter. The main switch and auxiliary switch alternate with a dead time, performing active clamp operation. Additionally, the "Magnetic Amplifier Output Circuit" allows for direct control of the voltage on the secondary side of the transformer by using a magnetic amplifier in the output circuit, making it easy to configure power supplies with multiple outputs. 【Features of the Partial Resonant Inverter (NH)】 ■ The circuit resonates partially only during the turn-on/off of the inverter ■ Achieves reduced switching losses and low noise ■ Alternates with a dead time between the main switch and auxiliary switch, performing active clamp operation *For more details, please refer to the PDF materials or feel free to contact us.

High-capacity switching power supply "Isolated System Interconnection PCS"

High-capacity switching power supply "Isolated System Interconnection PCS"

No leakage current or ground current flows from the system side due to the direct current ground.

The "Isolated Grid-Connected PCS" is a switching power supply that, due to its high-frequency isolation, does not allow leakage current or ground fault current from the grid side through the DC ground. Thanks to high-frequency isolation, commercial transformers are unnecessary, making it lighter, smaller, and more economical due to lower total costs. Additionally, it is not limited to V(S) phase grounding. Since the inverter is configured with three legs and is isolated, there are no grounding constraints, allowing for connections without restrictions on AC wiring methods. *For more details, please feel free to contact us.*
