Power Supplies with Terminal Connectors Selection Guide: Technical Criteria & Application Standards
Power Supplies with Terminal Connectors selection guide: technical parameters, mounting and compliance standards, and Delta Electronics comparison.
Power supplies with terminal connectors are switch-mode power supplies in metal cases, fixed to the mounting surface (panel-mounted), whose input and output cables connect to a terminal block on the housing. They are used inside machines and devices or on the panel mounting plate to supply automation components, electronic boards and general DC loads. The products in this category are the Delta Electronics PMT series: they are fed from a single-phase AC mains, provide 12 V, 24 V and 48 V DC output, and are listed in ratings such as 35 W, 50 W, 75 W, 100 W, 150 W, 200 W and 350 W. Select the output voltage according to the load to be supplied, the power and output current according to the total current of the load, and the housing size according to the mounting location. The product data gives the input as 90-264 V AC; according to the manufacturer's data, on some models of the series the input range is set with a switch on the housing, so verify the switch position before energizing. A power supply with terminal connectors is screwed to the mounting surface; it should not be confused with a DIN rail power supply that clips directly onto the DIN rail. The Power Supplies with Terminal Connectors category on Welibaba includes 21 active models from leading manufacturers such as Delta Electronics.
Key Technical Parameters for Selecting Power Supplies with Terminal Connectors
To specify the right Power Supplies with Terminal Connectors model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Supply Type / Input Voltage | 90–264 V AC | Verify against project schedule and load calculation |
| Phase Type | 1 Faz | Verify against project schedule and load calculation |
| Power | 100 W, 150 W, 200 W, 35 W | Verify against project schedule and load calculation |
| Output Current | 0.8 A, 1.1 A, 1.5 A, 1.6 A | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Power Supplies.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Perforated Type Power Supplies, DIN Rail Power Supplies.
