| J | The number of parallel dual-channel aging products: | There are 192 power supplies of 100W/10A or less, 96 power supplies
of 200W/20A or less, and 48 power supplies of 400W/40A or less |
| 3 | Introduction to the electronic control and temperature control
devices of the power aging trolley: |
| A | Wiring method: | AC port: Mobile cable + speaker clamp; DC ports:
5.5*2.1/5.5*2.5/4.0*1.75/3.5*1.35,One 4DC female socket each +
parallel switch + speaker clamp |
| B | Panel function keys: | Input AC voltage display, start switch, emergency stop switch |
| C | Temperature control accuracy in the product area: | Temperature control range: Room temperature to 55℃, ±5℃ |
| D | The temperature control principle of the product area: | Low-temperature heating, over-temperature exhaust |
| E | Power distribution and control methods for trolleys: | 220V three-phase five-wire power distribution; Computer monitoring
and manual electronic control |
| F | Distribution power of trolley: | 100W*192 units /0.80=24KW. The efficiency of the tested power
supply is calculated at 80% |
| G | Control mode: | The electrical control system features manual/automatic switching.
During aging, it is monitored in real time by a computer. The
control cabinet takes in three-phase 380V and outputs
90V/120V/240V/277V, simultaneously controlling 4 aging cabinets
(optional for customers) |
| H | Thermal insulation device: | The product area is equipped with aluminum alloy frame tempered
glass doors and air ducts on both sides |
| I | Safety protection: | Equipment grounding protection, leakage switch protection, smoke
alarm and automatic power-off protection, etc |
| 4 | Introduction to the main functions of the system: |
| A | Applicable to LED power supplies, power adapters, chargers,
switching power supplies, and industrial control power supplies |
| B | Free configuration of self-developed power supply aging dedicated
monitoring software, with independent intellectual property rights
and no legal risks |
| C | The output terminal voltage, current and power parameters are
monitored by using programmable electronic load modules |
| D | The aging-specific monitoring software enjoys a free upgrade
service and has powerful scalability, saving repeated investment in
equipment |
| E | Aging parameters can be set for the entire vehicle, the entire
layer, and individual products |
| F | Aging parameters, time setting,ON/OFF timing editing (for the
on-off test of the product under test), support for automatic
voltage switching, load transformation and other functions are
programmable |
| G | The function of automatically and regularly turning off the power
supply when the aging of the tested power supply ends is convenient
for unattended operation |
| H | The computer automatically displays the quality of the tested power
supply products. The window shows multiple vehicles for centralized
management, saving operators and improving production efficiency |
