The special feature of the D5 PWM pump from Lowara is the optimized PWM input, which can be controlled with practically any PWM output designed according to Intel specifications. This enables PWM control of the speed between 800 and 4800 revolutions per minute .The D5 PWM pump conveys up to 1600 liters per hour through the water cycle at a delivery head of up to 3.65 meters. The power supply is via a 4-pin Molex connector, which also enables an alternative control via the voltage.Note: A suitable pump housing is required for operation. The pump electronics are not waterproof, under no circumstances allow them to come into contact with water - no diving operation possible!Specification:- Dimensions: 70 x 72 x 82 mm (L x W x H)- Weight: 235 g- Head (12 V): 3.65 m- Speed: 800 - 4800 rpm- Throughput: max. 1600 L / h- Pressure: max. 10 bar- Operating voltage: 8 - 24 V- Power consumption: 32.16 watts (at 12 V)- Coolant temperature: 10 - 90 C- Connections: 4 pin Molex (power supply) 4-pin PWM with speedometer signal
