Advanced Energy Adds NeoPower Module and Open-Frame PSU

Advanced Energy has rolled out two power products: a dual-output 24 V/24 V module for its NeoPower configurable AC-DC family, and the SLB350, a 350 W open-frame supply aimed at industrial OEM designs.

While they target different design styles, both products aim for the same practical outcome: reducing the amount of custom power work engineers must do to meet emissions, safety, and thermal requirements in real enclosures.

NeoPower Adds More Rails Per Chassis

NeoPower is Advanced Energy’s configurable platform, comprising a chassis populated with output modules to create multi-rail supplies. The addition is a dual-output 24 V/24 V module in a 2.5-inch form factor that Advanced Energy describes as delivering up to 400 W, with a higher output count rather than a new chassis rating.

Advanced Energy stated that the module enables up to 16 isolated outputs per supply, which is important for systems that need multiple independent 24 V domains (with their own control and protection) across loads such as motion, I/O, pumps, or instrument subsystems.

Advanced Energy’s NeoPower documentation provides more detail on how the dual-output “slot” looks electrically. The dual-output 24 V module (listed as model 1D 2424M) is shown with each rail adjustable from 2.4 V to 28.8 V and up to 7.8 A, with remote sense support (500 mV compensation). The same table lists the maximum output power as 150 W per output.

Those ranges are worth calling out because they describe how NeoPower is meant to be used: less like a fixed 24 V brick and more like a programmable source that can be trimmed for voltage drops, derating, or downstream conversion needs. NeoPower also supports digital communication for control and monitoring using MODBUS RTU, with optional adapters called out for other protocols.

The module’s other headline specs are really platform specs, including compliance with IEC/EN/UL 62368-1 for industrial equipment, IEC/EN 60601-1 for medical, and SEMI F47 for semiconductor tools, and ties the module to digital control from a single AC input.

For designers new to the NeoPower family, the chassis endpoints provide useful context. NP08 is positioned as an “up to 4000 W” configurable supply with eight output slots and 18 W/in3 power density, while NP05 covers up to 2400 W with five slots and 17 W/in3 power density.

SLB350 Is Built around EMI and Thermal Headroom

The SLB350 is a more traditional single-output open-frame PSU, positioned for applications such as stage lighting, test and measurement, automation, robotics, and battery charging.

Advanced Energy leans hardest here on compliance; the company states that the SLB350 is certified to EN 55032 Class B for conducted and radiated emissions, meets EN 61000-6-2 immunity requirements for heavy industrial environments, and also addresses IEC/EN/UL 62368-1.

The compact 3 x 5-inch open-frame configuration with outputs from 12 V to 48 V, and the product page expands the lineup to 12 V, 24 V, 48 V, and 56 V variants. The product page lists a 90 VAC to 264 VAC input range.

Advanced Energy rates the unit at up to 350 W with airflow or 200 W under convection cooling, with operation from -10°C to 70°C and “up to 60°C before derating.” Advanced Energy states that the supply maintains full power at elevated ambient temperatures and limited airflow, and frames the product as a way for OEMs to reduce costs without sacrificing reliability.

Together, the two releases give engineers two different paths depending on architecture: add rails inside a configurable multi-output platform, or drop in a compact, standards-focused single-output supply where EMI and temperature behavior are the first-order constraints.
