Alpha 1000 Handbook

Part Number 17027

Input Parameters

Adjustment and Derating.

The Alpha 1000 series is designed to provide a max output power of 1000W at nominal output

voltages. The following procedure must be used to ensure the PSU is operated within its ratings:

a Calculate the user for power for each module (Volts x Amps).

b Total power for slots 1-3 must be

≤720W. Total power for slots 4-7 must be ≤ 600W.

Total power (slots 1-7) not exceeding value stipulated in unit limitations table

c Calculate user ampere turns (Amps x turns) for each module.

d Add total ampere turns: Slots 1-3

≤120. Slots 4-7 ≤120. Total of slots 1-7 ≤ 200AT.

NOMINAL INPUT VOLTAGE RANGE 94.4 - 240VAC or 133VDC-328VDC

MAX. INPUT VOLTAGE RANGE 85-264VAC or 120-360VDC

INPUT FREQUENCY 47-63Hz

MAXIMUM INPUT CURRENT 16 AMPS or 11 AMPS DC

INRUSH CURRENT <50 AMPS

Module Limitations

1 For B, BB, Q, L and Z modules in slot 7, max output current is 15A.

2 For D and E modules in slot 7, max output current is 5A

3 For G modules in slot 6 & 7, max output current is 15A.

4 For C, CH, CL, CM modules in slot 7, max output current is 10A.

5 For S modules in slots 5 and 6 max output current is 77A and in slots 6 and 7 max

output current is 67A.

6 For C and CH modules the max output current is 12A for output voltages > 12V.

7 For J modules the output current derates linearly by 0.25A per volt above 40V.

8 For H and N modules with output > 29V, max output current is 1A .

9 When using remote sense, the max output voltage will be reduced by 0.5V for L, S, T,

Q and R modules, and by 1.0V for C, CH, CL, CM, D, F, G, J, M, K, N, U Modules.

10 Ampere turns for J module is calculated as AT=(output current + 15A) x 4.

11 Adjusting output voltage beyond the stated range may cause overvoltage protection

(OVP) to operate, whereby all outputs will turn off. To reset OVP, turn back output

voltage adjustment and remove the mains supply fpr 30 seconds.

Output Parameters

Servicing

These products are not customer serviceable. Repairs may only be carried out by TDK-Lambda

Limited or their authorised agents. These products are not authorised for use as critical components in

nuclear control systems, life support systems or equipment for use in hazardous environments without

the express written approval of the Managing Director of TDK-Lambda Limited.

Energy Hazards and SELV

Certain modules are capable of providing hazardous energy (240VA) according to output voltage set-

ting. Final equipment manufacturers must provide protection to service personnel against inadvertent

contact with these module output terminals. If set such that hazardous energy can occur then the

module terminals or connections must not be user accessible.

Approval Limitations: Use in North America (AC units only)

When this product is used on 180VAC-250VAC mains with no neutral, connect the two live wires to

L(live) and N (neutral) terminals on the input connector. In this instance double pole fusing is required.

High Voltage Warning

Dangerous voltages present within the power supply. Do not remove covers.

External Hot Surfaces

Section 6 of the Health and Safety at Work Act requires that manufacturers have an obligation to

protect service engineers as well as users. In order to comply with this, a label must be ﬁ tted to these

products which is clearly visible to service personnel accessing the overall equipment, and which

legibly warns that surfaces of these products may be hot and must not be touched when the products

are in operation

Safety Earthing Screw

On products with an enclosure, special safety earthing screws are used which connect the cover to

the chassis. They must not be removed.

Safety Class of Protection

These products are designed for the following parameters : Material Group IIIb, Pollution Degree 2,

Overvoltage Category II, Class 1 (earthed), Indoor use as part of an overall equipment such that

the product is accessible to service engineers only.
