Braking Devices VersiBrake [36A]

Product catalog summary

Specifications:
The document outlines the specifications for a DC braking device suitable for asynchronous motors. It features microcontroller control, wear-resistant and maintenance-free operation, and is designed for easy mounting, including retrofitting into existing plants. The device supports special voltages up to 575V with an option "B" and is designed for snap-mounting onto a 35mm top-hat rail with a degree of protection IP 20.

Functionality:
The braking device is controlled via a motor contactor and includes standstill detection, braking current limitation to rated device current, remanence time optimization, and infinitely adjustable braking current. It provides potential-free outputs for motor contactor interlocking during braking, fault signaling relay, and braking contactor. Additionally, it includes temperature monitoring of the power module.

Options:
Optional features include star-delta starting control (D) and a wide-voltage-range of 200…575V (B). Control voltage options are 24VAC or 230VAC, which should be specified upon order.

Technical Data:
The braking devices, VB 230-36 and VB 400-36, operate at mains voltages according to DIN EN 50160 (IEC 38) with specific voltage ranges and power draw of electronics at 6 VA. They are recommended for rated motor currents up to 17A with a rated device current of 36A. The braking voltage ranges from 0 to 130VDC for 220/240V and 0 to 220VDC for 380/415V, with a maximum braking time of 15 seconds. The contact rating of the output relay is 6A/250VAC or 6A/30VDC, and the delay time for reduction of residual e.m.f. is self-optimizing between 100 and 2500ms. The maximum cross-sectional area is 2x 2.5mm² per terminal, and the ambient/storage temperature ranges from 0°C to 45°C and -25°C to 75°C, respectively. The device weighs 1 kg.

Recommendations:
For the operation of IE3 motors, it is recommended to consider the higher starting and braking currents when dimensioning soft starters and DC brakes. It is advised to design these devices one size higher for IE3 motors.

Dimensions and Connection Diagram:
The mounting dimensions for the VB series are provided as 100mm (A), 73mm (B), and 120mm (C). The connection diagram emphasizes ensuring correct terminal-phase connections between the braking device input (L1, L2) and output (T1, T2).

Typical Applications:
The braking devices are typically used in applications such as saws, conveyors, woodworking machines, grinding machines, and other similar equipment.
