HEP1000 Series - Release Notes

HEP-1000 Series - 1,000W Harsh Environment Power Supplies

HEP1000 Harsh Environment Series Banner

In recent years, customers in the 5G, data center, laser equipment, and EV charging equipment business, are demanding more complex functions and higher reliability from power supplies. As a response to the market demand, MEAN WELL has heavily invested R&D resources, in software and hardware, to develop the HEP-1000. This is an intelligent power supply for harsh environments. In addition to the low-voltage 24V and 48V models commonly used in the industry, this power supply also is available in a 100V high-voltage model to meet the needs of those with high-voltage applications such as lasers and for charging.

The HEP-1000 is a 1,000W industrial AC/DC power supply that may be used in harsh environments. HEP-1000 supplies are enclosed in an aluminum casing with a unique fan-less design. The case is fully encapsulated with silicone gel, which provides effective environmental protection allowing for installation in dusty and humid environments. The HEP-1000 can also operate in an environment with up to 10Gs. These are robust power supplies that can significantly reduce maintenance costs and ensure that equipment will operate reliably.

Another key feature of the HEP-1000 is the integration of power supply and charger into a single model. Customers can switch between the power supply and charging mode through the MEAN WELL accessory (SBP-001) or communication interface. This greatly reduces the number of models and stocking requirements (SKU). The HEP-1000 has built-in three-stage programmable charging curves for constant current, constant voltage and floating charge capabilities, allowing users to define their own charging parameters. It is suitable for lead-acid batteries such as gel, flooded and AGM, as well as lithium ion (lithium iron, lithium manganese) batteries. This will meet the diverse charging needs of electric vehicles and other electric devices. Electrical performance and status of the charger can be monitored through communication functions. Constant monitoring of the electrical parameters, such as output voltage, current, and protection alarms status, may prevent disastrous accidents such as overheating of batteries due to overcharging.

The standard HEP-1000 models are equipped with the PMBus communication protocol, and optional models with the CANBus communication protocol are also available for customers to purchase. These intelligent communication functions allow the power supply to be seamlessly integrated into different types of high-end system, making it a controlled peripheral device that is integrated with the power supply. Benefits will include power saving, status monitoring, and fast communication between the system and power supply, making the HEP-1000 a suitable solution for data centers and Netcom devices with digital power management requirements. Additionally, the HEP-1000 has analog controlled programmable voltage and programmable current functions (PV/PC). Through external DC voltage signals, the output voltage and current level can be adjusted between 50%~125% and 20%~100% respectively. The ability to flexibly meet various load and control requirements makes the HEP-1000 suitable for burn-in equipment, charging equipment and laser applications.
