Low-power buck-boost DC/DC converters
Non-isolated buck-boost modules from 2 kW to 8 kW in 20 V to 170 V ranges, developed for stationary hydrogen generation and fuel cell forklift drivetrains where isolation overhead is not justified.
H-NS series
Model range
The H-NS series is developed specifically for stationary hydrogen fuel cell power generation and forklift drivetrains, where a non-isolated topology lowers cost and reduces mass without compromising the stack.
| Model | Max continuous current | Power range | Input voltage | Output voltage |
|---|---|---|---|---|
| H-NS120-120-120 | 120 A | 2–4 kW | 20–120 V | 20–120 V |
| H-NS120-120-140 | 140 A | 2–8 kW | 20–120 V | 20–120 V |
| H-NS170-170-140 | 140 A | 2–8 kW | 20–170 V | 20–170 V |
Applications
Fuel cell forklifts
Backup power systems
Modular option
ZIS Series Modular Isolated DC/DC Converter
The ZIS series is a modular isolated DC/DC converter used for voltage conversion across a wide input range, supporting customer customization in both module and complete-machine form.
Rated power options
600 W · 1.2 kW · 1.8 kW · 2.4 kW · 3.0 kW · 6 kW · 12 kW · 18 kW
Input voltage options
24 V · 48 V · 72 V · 96 V · 108 V · 144 V · 360 V · 540 V · 700 V
Installation
Module (integrated into other enclosures) or complete machine with independent enclosure
Cooling
Natural cooling / air cooling / liquid cooling
Isolated or non-isolated? The H-NS series is non-isolated by design and suits controlled, low-consequence installations. If your stack shares a cooling loop with an HV bus, or your installation is outdoors or mobile, specify an isolated converter instead. Our engineers will tell you which case yours is.
