Powerbox’s ENA100 and ENA200 power stage come with galvanic isolation of 500VDC and built-in protections and filtering, making products ready to use without additional components.
Powerbox, a power supply company, has introduced a series of power supplies for automotive applications and on-board Internet of Things (IoT). The solutions, ENA100 (100W) and ENA200 (200W), are based on a highly integrated components platform and low-profile planar magnetics, and are packaged in a plastic enclosure, which is IP21 and the boards are conformal coated to withstand high humidity, addressing the harsh environments found in the automotive industry, indicated the company.
To guarantee the highest levels of efficiency and reliability, the ENA100 and ENA 200 power stage uses specific components selected for robustness and high-reliability data and operated within a safe-band area. The series comes with galvanic isolation of 500VDC and built-in protections and filtering, making products ready to use without additional components.

As members of the Powerbox Automotive Line, the ENA100 and ENA200 units have been designed in response to the automotive electronics equipment manufacturer’s demand for standardised DC-DC converters built-in low profile packaging, lower than 20mm, isolated cases with an IP-class of 21, galvanic isolation, low conducted and radiated EMI and sustaining 2kV surges along with a requirement for simple installation and the ability to upgrade when more power is required, if new equipment is added.
Packaged in a 116mm x 88mm x 18mm polycarbonate housing, the ENA100 and ENA200 baseplate includes four mounting holes for mechanical attachment to a vehicle chassis or assembly plate. The low weight, less than 500g, contributes to excelling performances in vibration testing (5Hz to 50Hz, acceleration ±7,35m/s2).
Input and outputs of the products are equipped with 6.3mm industry standard connectors, along with an integrated LED, indicating the state of the output voltage.
The ENA100 and ENA200 series cover a large range of applications requirements from 10VDC input up to 120VDC (10V to 18V, 18V to 32V, 36V to 75V and 55V to 120V). Four output voltages, 12.5V, 14.5V, 24.5V and 28V will be available and, depending on the output voltage, in a range of output currents of 8A to 16A. The ENA100 and ENA200 also boast efficiencies of up to 96%.
Ready to use products, the ENA100 and ENA200 series incorporate efficient input filtering, short circuit protection with constant current limit set at about 110%, temperature protection with automatic recovery and intelligent power control, guaranteeing safe-gap operation. Aimed at conduction cooling, the ENA100 and ENA200 series can be operated from -20°C to 50°C ambient and up to 70°C baseplate.
Meeting road vehicle EMC and transient protection the ENA100 and ENA200 series comply with the standards EN61000-6-2; 4-2/3/4/5/6 and EMI EN55022B conducted and radiated. The ENA100 and ENA200 also comply with ISO7637-2 and EN12895:2000 immunity.
Easy to use and quick to interchange when upgrading systems, the ENA100 and ENA200 series are the intended power solutions for a range of applications in the automotive segment, including specific fork lifter, cleaning machines, assisted seats, surveillance and monitoring mobile equipment, detailed the company.
The ENA100 and ENA200 are the first two series' of a family, which will eventually include 400W models, non-isolated step-down converters and battery chargers. The ENA100-400 will complement the Powerbox Automotive line, which includes the ENA20 to ENA60.
The ENA100 and ENA200 products are RoHS II and REACH compliant.
