The importance of quality power supply in machine automation
PMT2 series – high stability and safety protection functions
Jul. 29, 2021
Faced with ever-increasing cost pressures and demands for improved performance, machine builders are actively seeking new automation solutions with improved cost/performance ratios. A machine’s automation system primarily consists of power and control components. For a smaller machine, these may be housed in one panel, whereas larger machines may require multiple panels, often one for control and another for power.
The main subsystems and components of machine automation system are:
motor control and drivers,
discrete and analog I/O,
human-machine interface (HMI).
Machine automation is highly critical in modern factories. Components used in machine automation must be reliable under any rigorous use. In the automated production process, a power supply is the basic component that requires high stability and safety protection functions. Delta’s power supplies are highly efficient for minimizing power loss from power supply units, thus maximizing savings on electricity bills. Some series provide intelligent overload protection in constant current mode, making them suitable for battery charging systems.

Open frame power supplies: it is easily distinguished without any casing. Highlights: compact design to save space, suitable for installation inside a device or equipment, certified for use in industrial applications and medical industries.
Cost effective 35 W – 350 W PMT2 series in low profile design
PMT2 series is the latest series of panel mount power supply from Delta Electronics. PMT2 panel mount power supply series now offers power ratings of 35 W, 50 W, 75 W, 100 W, 150 W, 350 W single output and 75 W dual output. A wide range of 12 V to 48 V outputs are available for 35 W – 350 W models, while the two 75 W dual output models are available in 5 V/12 V and 5 V/24 V. This series is designed based on a common profile of ≤ 30 mm height and can withstand shock and vibration requirements (in accordance to IEC 60068-2-27 and IEC 60068-2-6 respectively). Despite the smaller form factor, the PMT2 can still operate a wide temperature range from -30 °C to +70 °C. The lightning surge immunity meets IEC 6100-4-5, Level 4 (CM: 4 kV, DM: 2 kV).
Safety approvals includes IEC/EN/UL 62367-1 and IEC 61950-1 while most models meet IEC/EN 60335-1, IEC/EN 61558-2-16 for household electrical appliances safety approvals. EMI standard complies to EN 55032, Class B.
Highlights & features:
Household appliances approvals according to IEC/EN 60335-1, IEC/EN 61558-1 and IEC/EN 61558-2-16 (except 350 W models).
Over voltage category (OVC) III and Pollution degree 3 (except 350 W models).
No load power consumption: < 0,3 W for 35 W, 50 W, 75 W, 100 W, 75 W Dual models; < 0,5 W for 150 W models; < 0,75 W for 350 W models.
Low profile design: ≤ 30 mm height.
Wide operating temperature: -30 °C to 70 °C (support -40 °C cold start).
Conforms to harmonic current IEC/EN 6100-3-2, Class A.
The PMT2 series is designed for cost competitive applications without compromising on quality and reliability. The products have an expected lifetime of 10 years. All Delta industrial power supplies including the PMT2 series are fully compliant with RoHS Directive 2011/65/EU environmental protection.
