DIN Rail Power Supply, 240 Watt

◆

High efficiency: 88%

◆ ACin autoselect: 115/230V (@ DP177.102, 104)

◆ WxHxD = 225x110x130mm

◆ Parallel mode automatic load sharing

◆ Over-Temperature Protection (OTP)

◆ Over-Voltage Protection (OVP)

◆ Meets EMV standards

VDE 0160/2, EN 61000-4, NAMUR,
EN 50081-1 (EN 55022/B) and EN 50082-2

◆ Design meets VDE 0551

The DP 177 is a compact solution for applications
supplying controllers, sensors, actuators in industrial
plants, and heavy machines.
Output voltage is stable over the total load ran ge,and
have excellent ripple and noise values below 20mVp p
at 24V DC.

Multiple units can supply current in parallel, by con­necting their symmetry terminals to ensure each supp­lies an equal share of the current. Light weight and
small size allow quick and easy installation on DIN rails.

Line voltage disturbance and noise im munity satisfies
EN 61000-4 and VDE 0160 pulses (class 2 for total
load range!). The unit is over-voltage and short-circu it
protected. Isolation is equivalent to safety transformers
according to VDE 0551, and it meets VBG 4.
