Detailed Product Description: | Features energy moving unit: 1 heavy duty series CDBR-2 voltage, power range:... 220V-460V; 200-315kw; built-in cooling fan 3 applied: for a variety of imported and domestic low-voltage inverter (three phase induction, permanent magnet synchronous motors). 4 security: the use of advanced power electronics technology and high-performance IGBT as a switching device, automatic voltage tracking, quality and safety, special design, you can use an ordinary resistor, having to choose non-inductive resistor. 5 Economy: cost-effective, quality can be comparable with similar imported products, power range, each power range has a single brake unit can be used. Can also be used in parallel detailed technical description: 2.1 Technical Specification braking voltage tracking mode 1ms response time less noise filtering algorithm with multiple grid voltage 300V-460Vac ,45-66HZ operation voltage 670Vdc, the error voltage 10V ± 2V hysteresis protection / thermal overheating, over-current, short circuit / built-in cooling fan noise filtering has protection class IP00 Specifications: Model Rated current peak current minimum resistance Dimensions / Size (Unit: mm) L L1 W W1 H CDBR-4030C 15A 50A 20 240 Euro 228 100 70 153 CDBR-4045C 25A 75A 13.6 Europe 240 228 100 70 153 CDBR-4075C 30A 100A 10 Europe 315 280 215 200 115 CDBR-4110C 50A 150A 6.8 Europe 320 304 187 120 163 CDBR-4160C 70A 200A 5 Europe 320 304 187 120 163 CDBR-4220C 85A 300A 3.3 Europe 410 380 254 190 203 CDBR-4300C 110A 400A 2.5 Europe 410,380,254,190,203 * table rated current is the maximum current braking unit and braking work product of the maximum frequency Kc permitted value that does not mean that the brake unit will be able to continue to work in the current, but its cooling conditions related to the work environment. Electrical installation: Installation braking unit to be mounted vertically on a non-flammable solid mounting surface, that is, to ensure that the internal braking unit direction is vertical fins to facilitate natural convection of air. Brake unit will heat during operation, so the braking unit and other components mounted around a certain distance to empty, depending on the size of the optional power brake unit, the distance can be vacated between 150mm-500mm selection. Selection braking unit: Selection braking unit is its rated current and peak current basis, to ensure that the brake unit to work properly, you must ensure that the maximum flow through the brake unit is less than its current peak current, and the maximum Kc and braking frequency current is less than the product of the rated current. Under normal circumstances, in order to facilitate the selection, you can follow the instructions directly from the load of 4.1 to select the appropriate look-up table type brake unit. At the request of a more accurate picture, you can refer to Section 4.2 to choose. General Load Selection Table: In the actual average braking power is unclear circumstances, you can simply load into two types of light and heavy loads, and the chart below to select the type brake unit: Table light load is refers to the actual load is smaller, lower rated power of the motor is less than 60% of the occasion or the actual braking rate, within 200 seconds of the braking duty cycle of less than 10% of cases, overloading refers to the actual load is greater than the motor nominal power 60%, or within 200 seconds, the actual braking time duty cycle greater than 10% of the occasions. An extensive; Special design can use an ordinary resistor, having to choose non-inductive resistor chopper voltage is adjustable for a variety of low-voltage inverter. 2 economy: cost-effective, quality can be comparable with similar imported products, lower prices, are inverter brake, brake circuit economical and practical accessory products. 3 can be used in parallel, using the book design, can be installed in parallel without gaps DBU2015-195 * 80 * 134 | voltage level 200V ~ AC30 | Rated Current (A) 15 | 10 European DBU2030-195 * 80 * 134 | 200V voltage class ~ AC30 | Rated Current (A) 30 | 6.5 Europe DBU4030-195 * 80 * 134 | voltage rating 380V ~ AC46 | Rated Current (A) 15 | 20 European DBU4045-195 * 80 * 134 | voltage rating 380V ~ AC46 | Rated Current (A) 25 | 16.3 Europe DBU4110-327 * 180 * 202 | voltage rating 380V ~ AC46 | Rated Current (A) 70 | 6 Europe DBU4220-327 * 180 * 202 | voltage rating 380V ~ AC46 | Rated Current (A) 85 | 3 Europe DBU4300-327 * 180 * 202 | voltage rating 380V ~ AC46 | Rated Current (A) 120 | 2.5 Europe DBU6220-327 * 180 * 202 | voltage level 3AC690 | Rated Current (A) 85 | 6 European DBU11220- 327 * 180 * 202 | voltage level 3AC690 | Rated |
