Lab Furniture Physics Laboratory Table for School Use

Teacher (Demo) Bench 2400*700*850mm

Top Material: use 25mm thick melamine fireproof board, the body 16 fireproof board, easy to clean, waterproof, fireproof, double sides can be flipped to use.

Bench Body: aluminium alloy frame structure, the frame use GB Ф50 mm±1.0mm round tube as standing legs, the horizontal tube is square tube 32x28±1.0mm, the wall thickness for the alum-alloy profile is not less than 1.0mm(±0.2mm), electrostatic spraying on aluminum alloy surface, the connecting joints are ABS engineering plastics made.

Structure: demo bench is modular design, the teacher demo power supply and students’ power supply control device can be put in the middle part, the computer host, DVD, amplifier, center control host can be put within left side of the bench.

Foot Pad: use special mould ABS injection molding foot pads, with adjustable height, can effectively prevent bench body from damp, extending the equipment lifetime.

Teacher General Power Supply

• leakage protection switch, work indicator light use China made high quality products, 220v AC output sockets (2,3-hole socket) use China made high quality products.
• low voltage AC power supply: 2-30V can be adjustable(2v per gear), rated current 8A(automatic protection for short circuit and overload, automatic reset)
• DC stabilized voltage source: 1.5-1.8V continuous adjustable, rated current 6A, 18v-24v rated current 3A(automatic protection for short circuit and overload, automatic reset), 85 pointer gauge display.
• DC big current output: 9V/40A, 8s automatically disconnect.
• Teacher socket power supply: 220v AC, load current 10A. 5-hole(or 3-hole dual purpose)AC power supply socket 1 pc. is built within the middle drawer of the demo bench.                   A. Student bench AC 220v power supply is controlled by teacher, each group is controlled by air switch, 4 groups in total, and matched with leakage protection switch.                       B. Teacher control uniformly student bench low voltage power supply, AC each gear 2v, 15 gears in total. The DC is fine tuning under control.

Student Bench 2400*600*760mm

Top Material: use 25mm thick melamine fireproof board, the body 16mm thick fireproof board, easy to clean, waterproof, fireproof, its cross section is sealed with hard PVC by imported edge sealing machine in condition of high temperature& hot pressing.

Main body: the structure is alum-alloy frame, the frame use epoxy resin electrostatic spraying on aluminum alloy surface. table hole is made of melamine fireproof board 25mm thickness.

Connecting Joints: ABS special connection joints, assembly seam is tight, firm and no loose, no deformation, beautiful and durable.

Foot Pad: use special mould ABS injection molding foot pads, with adjustable height, can effectively prevent bench body from damp, extending the equipment lifetime.

Student Power Supply

• AC output: 1.5-16V, 8 gears is adjustable, with ammeter indicating, ammeter precision is not less than 2.5 grade, rated current ≥2A, with overload protection function.
• DC stabilized voltage source: output voltage 1.5V, continuous adjustable (precise 2V-24V, each gear 2V, fine tuning 1V), rated current for gear 2V-6V is 6A, gear 8V-12V is 4A, gear 12V-24V is 2A, overload, overcurrent short circuit automatic disconnection protection.
