Miniaturized step-up voltage regulator – Standard passive dissipation – Input 40V to 60V – Output 72V / 21A / 1500W – SUR-4060-7221-3A

Description

Input Vin: 40 to 60V (48V battery for example)
Output: 72V / 21A (25A peak) / 1.5kW
Nominal efficiency: 98%
Half-brick type module for this special boost converter

Line regulation, load regulation, thermal drift (ΔT° = 50°C): better than 1%

Overload limitation: with automatic hiccup of the output voltage Vout, lowered to the level of Vin, allowing very high starting currents, for example for engines (optional input fuse oversized depending on the starting current)

Case temperature: – 40°C to + 100°C
Ambient temperature: – 40°C to + 85°C
Thermal resistance of the case: 6°C / W
Thermal protection: lowering of Vout at the level of Vin (automatic rise after cooling)

Protection against moisture, vibrations and shocks: IP67 sealing

Standard case 2A equipped with four special screw connectors:

• dimensions: 85 x64 x 32 mm / weight: 190g
• screwable on a thermally conductive support
• mountable on heatsink type “112”

Standard heatsink, type “112”:

• can be mounted on wall, through two holes
• can be mounted on DIN rail, on its back
• can be mounted on DIN rail, on its side

Standards and particularities:

• MTBF > 500 000 hours at 30°C
• CE / UL / cUL 60950-1 marking
• RoHS
