Fuji Electric, Power supplies - AL35

AL35 supplies are available in 1 to 4 outputs and are particularly suitable for the implementation of converters in two wires technology (loop powered 4 ... 20mA). The isolation between each output eliminates ground loop problems that may affect the measurement. Each output being independent and of low power, the risk of damage to the material is discarded compared to the use of a single high output power supply. The independence of each loop greatly increases the reliability of the system. The outputs allow all wiring combinations to suit specific needs, their use in serial or parallel can achieve balanced output, increase the output current or voltage.

Fuji Electric instrument power supplies with isolated outputs for 4-20mA current loop.

These supplies are available in 1 to 4 outputs and are especially suitable for the implementation of two wires technology converters (4-20mA current loop powered). The isolation between each outputs eliminates ground loop problems that may affect the measurement. Each output being independent and of low power, the risk of damage to the material is discarded compared to the use of a single high output power supply. The independence of each loop strongly increases the reliability of the system. The outputs allow all wiring combinations to suit specific needs, their use in serial or parallel can achieve balanced output, increase the output current or voltage.

Description:
- The SMPS version allow high power density without heating due to its high efficiency. It also adapts to a wide range of input voltage (AC or DC) - The linear version is particularly suitable for applications requiring a very stable output voltage or noise-free.

Specifications:
- 1, 2, 3 or 4 isolated outputs allowing serial or parallel coupling, in order to obtaining exotic or symmetric output voltages, or to increase the avail- able output current.
- 24 Vdc typical output voltage
- any output voltage available on request from 0 to 24Vdc and up to 96 volts by coupling
- permanent short circuits protection,
- overload protection,
- thermal protection (output power limitation),
- natural convection cooling,
- embedded EMC filter in accordance with EN55022 class A,
- regulated output voltage,
- output protection with transient voltage limiter 24V.



Features:
- DIN rail mounting,
- Protection rating IP20,
- Conformal coating,
- Green LED for main voltage presence,
- Connection by screw terminals, wire section up to 2.5 mm2.

Implementation and installation recommendations:
- primary protection with fuse (delayed 2A) recommended,
- maintain a spacing of 2 mm between device for natural convection.
