EL-R Series DC Power Supply – Precision & Silence with Linear Regulation
The Aim-TTi EL-R Series DC Power Supply is designed for engineers, technicians, and educators seeking high performance and silent operation. Utilizing linear regulation technology, the EL-R Series offers stable, low-noise outputs with high precision and reliability across single, dual, and triple channel configurations.
Versatile Output Options for Any Application
The EL-R Series includes a variety of voltage/current combinations to suit a wide range of applications:
- Single outputs: 15V/5A, 18V/3.3A, 30V/1A, 30V/2A, 30V/3A, 56V/1.1A
- Dual output: 2 × 30V/2A (EL302RD)
- Triple output: 2 × 30V/2A + 1.5–5V/2A auxiliary (EL302RT)
Every output features 4-digit digital meters for accurate voltage and current readings. The supplies operate in either constant voltage or constant current modes, with automatic crossover indication.
Compact Design with Silent Fan-Free Cooling
Built for bench or rack use, the EL-R series’ compact and space-saving design is combined with convection cooling, ensuring silent operation—ideal for quiet lab environments. (Note: some high-power models like the EX2020R use fan cooling.)
Connectivity and Remote Sensing
For remote operation or automation, select models offer RS232 or USB interfaces, allowing seamless integration into test systems. The local or remote sense switching ensures precision at the load point for demanding setups.
