ROAL custom low power LED drivers offer a combination of high reliability, high energy conversion efficiency and active LED temperature control. These single channel isolated AC/DC LED drivers can be designed to output a constant current of between 350mA and 1500mA at a voltage of between 20V and 60V.
Designed for color mixing and harsh environmental applications, ROAL's custom medium to high power LED driver platform offers high power, high reliability and high efficiency. The platform can provide custom LED driver solutions with single or multi output including color mixing, external DMX control and/or onboard memory with power levels from 80W to 400W.
Suited to high reliability and harsh environments, the ROAL medium to high power AC/DC digital PFC platform has been proven in the field with over 500,000 installations in a variety of demanding outdoor applications. Offering up to 2kW with either single or multiple outputs, the platform has an integrated digital PFC primary side and conversion efficiencies up to 90%..
ROAL's non-isolated high power boost platform was designed for central office and networking applications to compensate for voltage line drops which can cause outages. The DC/DC boost technology offers 96.5% conversion efficiency and can be introduced with dual ETSI or ANSI modes. The platform obtains extremely high power density and uses a digital control loop.
The high power DC/DC converter platform was designed for networking applications. Featuring noise emission compliance to EN55022 class B and immunity to EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-4-5, EN61000-4-6, EN300827 (TETRA), ETSI EN 300 385/6 Class B, FCC Part 15 Class B . These high reliability DC/DC converters have been used by the largest networking companies in the world to power their highend trunk routers.
Offering up to 2kW of power the ROAL custom battery charging platform integrates micro-processor charging stages control (IUoU), fan temperature controlled speed, soft start up and a variety of communication protocols including I2C, CANBus and PMBus. Featured diagnostics include output short circuit, open output fuse, output over voltage, internal over temperature, prolonged over load and fan failure.
