## **Specifications** ## **Voltage** - Floating outputs on spring terminal block with levers for 2,5 mm2 (AWG12) wires. - Output voltage : adjustable from 5 to 29 V by 12 position switch, and fine adjustment switch positions : 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28 Volts. Fine adjustment range : ± 1 Volt, whatever the switch setting 12 and 24 V lead-acid battery charger positions identified by two LED indicators. - Regulation : < 30 mV at 5 V and < 10 mV at 29 V for a load variation from 0 to 100%. < 1 mV at 29 V @ 2,1 A and < 4 mV at 5 V @ 4 A for ±10% line variation. - < 30 mV at 5 V and < 10 mV at 29 V for a load variation from 0 to 100%. - Dynamic regul. : - < 1% to 29V and < 5% to 5 V for a load change from 10 to 90%. - Ripple : < 3 mV rms including : - < 3 mV peak to peak of the 100 kHz signal - < 4 mV peak to peak of the 100 Hz signal - < 10 mV peak to peak of switching transients - Hold-up time : 25 ms at half load and 12 ms at full load. (190 V line input) - Indicators : Green LED indicator : “power supply operating” Yellow LEDs indicator : “12 V and 24 V battery charger position” Red LED indicator : “status, output fuse broken" or "overheat" The yellow LEDs also indicate battery-backed operation. **Current** - Max I : 4,2 A in short circuit condition 4 A to 5 V, 3,5 A to 12 V, 2,5 A to 24 V and 2,1 A to 29 V - **Battery charger** - Rated capacity of the lead-acid batteries with elctrolyte free : 35 Ah for 12 V and 20 Ah for 24 V. - Minimum capacity of the lead-acid batteries sealed : 10 Ah for 12 V and 7 Ah for the 24 V. (In all the cases, to refer to the note of the batteries manufacturer) **Remote sensing** - Correction of the voltage drop in the wires (4 wires method) • Input on disconnect scribe terminal blocks for 2,5mm2 wires (AWG12) • Correction : Max 3 V (1,5 V per wire) • Ripple : < 30 mV for a load variation from 0 to max. **Power** **==> picture [267 x 157] intentionally omitted <==** **----- Start of picture text -----**
